    Stress-tests the four cached Java {@code JMethodID}s the new + * code exercises on every streaming/async dispatch: + *

      + *
    • {@code java/io/InputStream.read([B)I} — pulled by + * {@link VesperaBridge#dispatchFullStreaming}
      • + *
    • {@code java/io/OutputStream.write([BII)V} — pushed by + * {@code dispatchFullStreaming} and + * {@code dispatchStreamingWithHeader}
      • + *
    • {@code java/util/function/Consumer.accept(Ljava/lang/Object;)V} — + * header callback fired by {@code dispatchStreamingWithHeader} + * before the first body byte reaches the {@code OutputStream}
      • + *
    • {@code java/util/concurrent/CompletableFuture.complete(Ljava/lang/Object;)Z} — + * async completion path used by {@code dispatchAsync}
      • + *
    + * + *

    If any of those cached method IDs resolves the wrong + * class / signature / vtable slot, calling them through + * {@code call_method_unchecked} will SIGSEGV the test JVM — and the + * abnormal Gradle worker shutdown IS the test failure signal. + * The prior E2E run never exercised the cached path because + * {@code StreamingThroughputBenchTest} is gated behind + * {@code -Dvespera.bench=true} (see {@code @EnabledIfSystemProperty}). + * This test runs unconditionally as part of the normal {@code test} + * task to lock that gap. + * + *

    Verification per iteration: + *

      + *
    • Random 1 MiB body driven by a single shared {@link Random} + * seed ({@code SEED}) for deterministic replay.
      • + *
    • SHA-256 of the body that left the JVM == SHA-256 of the body + * that came back through {@code /echo/stream}.
      • + *
    • For the bidirectional path: {@code InputStream.read} fired + * multiple times (multi-chunk pull) AND {@code OutputStream.write} + * fired multiple times (multi-chunk push), proving the cached + * method IDs were called repeatedly per dispatch. With the + * default 64 KiB streaming chunk size and a 1 MiB payload the + * Rust side performs ~16 pulls + 1 EOF read and ~16 pushes + * per iteration.
      • + *
    • For the header-streaming path: {@code Consumer.accept} fires + * exactly once and before the + * first {@code OutputStream.write}; header decodes as wire JSON + * with status 200.
      • + *
    • For the async path: {@code CompletableFuture} completes + * successfully with a valid wire response (status 200, body + * matches by SHA-256).
      • + *
    + * + *

    Iteration budget — sized to keep wall-clock for + * the whole class comfortably under ~90s on a normal developer machine + * while pushing the cached paths thousands of times: + *

      + *
    • {@code dispatchFullStreaming}: {@value #BIDI_ITERATIONS} × 1 MiB + * → ~16 000 cached {@code InputStream.read} calls + ~16 000 + * cached {@code OutputStream.write} calls

    • {@code dispatchStreamingWithHeader}: {@value #HEADER_STREAMING_ITERATIONS} + * × 1 MiB → ~{@value #HEADER_STREAMING_ITERATIONS} cached + * {@code Consumer.accept} calls + ~8 000 cached + * {@code OutputStream.write} calls
      • + *

It transforms all your styles at build time, completely eliminating runtime overhead while providing full CSS-in-JS syntax coverage.\n\n### The Problem with Traditional CSS-in-JS\n\nTraditional CSS-in-JS solutions force you to choose between:\n\n- **Developer Experience**: Intuitive APIs, co-located styles, dynamic theming\n- **Performance**: No runtime overhead, fast page loads, optimal Core Web Vitals\n\nLibraries like styled-components and Emotion offer great DX but execute JavaScript at runtime to generate styles. Zero-runtime alternatives like Vanilla Extract sacrifice some flexibility for performance.\n\n### The Devup UI Solution\n\nDevup UI eliminates this trade-off entirely. Our Rust-powered preprocessor analyzes your code at build time and handles every CSS-in-JS pattern:\n\n- **Variables** — Dynamic values become CSS custom properties\n- **Conditionals** — Ternary expressions are statically analyzed\n- **Responsive Arrays** — Breakpoint-based styles are pre-generated\n- **Pseudo Selectors** — `_hover`, `_focus`, `_active` work seamlessly\n- **Themes** — Type-safe theme tokens with zero-cost switching\n\n### Key Advantages\n\n\n \n \n Feature\n Devup UI\n styled-components\n Emotion\n Vanilla Extract\n \n \n \n \n Zero Runtime\n Yes\n No\n No\n Yes\n \n \n Dynamic Values\n Yes\n Yes\n Yes\n Limited\n \n \n Full Syntax Coverage\n Yes\n Yes\n Yes\n No\n \n \n Type-Safe Themes\n Yes\n Limited\n Limited\n Yes\n \n \n Build Performance\n Fastest\n N/A\n N/A\n Fast\n \n \n

The macro parameter takes priority over the env var, which takes priority over the built-in default.\n\n| Parameter | Environment Variable | Default |\n|-----------|---------------------|---------|\n| `dir` | `VESPERA_DIR` | `\"routes\"` |\n| `openapi` | `VESPERA_OPENAPI` | none |\n| `title` | `VESPERA_TITLE` | `\"API\"` |\n| `version` | `VESPERA_VERSION` | `CARGO_PKG_VERSION` |\n| `docs_url` | `VESPERA_DOCS_URL` | none |\n| `redoc_url` | `VESPERA_REDOC_URL` | none |\n| `servers` | `VESPERA_SERVER_URL` + `VESPERA_SERVER_DESCRIPTION` | none |\n\n## Common Patterns\n\n### Minimal — just a router\n\n```rust\nlet app = vespera!();\n```\n\n### With Swagger UI\n\n```rust\nlet app = vespera!(docs_url = \"/docs\");\n```\n\n### Write OpenAPI file + Swagger UI\n\n```rust\nlet app = vespera!(\n openapi = \"openapi.json\",\n docs_url = \"/docs\",\n title = \"My API\",\n version = \"1.0.0\"\n);\n```\n\n### Multiple OpenAPI output files\n\n```rust\nlet app = vespera!(\n openapi = [\"openapi.json\", \"docs/api-spec.json\"]\n);\n```\n\n### Custom route folder\n\n```rust\n// Scans src/api/ instead of src/routes/\nlet app = vespera!(dir = \"api\");\n```\n\n### With state and middleware\n\n```rust\nlet app = vespera!(docs_url = \"/docs\")\n .with_state(AppState { db: pool })\n .layer(CorsLayer::permissive())\n .layer(TraceLayer::new_for_http());\n```\n\n### Merging child apps\n\n```rust\nlet app = vespera!(\n openapi = \"openapi.json\",\n docs_url = \"/docs\",\n merge = [billing::BillingApp, notifications::NotificationsApp]\n)\n.with_state(app_state);\n```\n\n## The `.serve()` Extension\n\n`vespera!()` returns an `axum::Router`. Vespera adds a `.serve(addr)` extension trait that replaces the usual `TcpListener::bind` + `axum::serve(...)` boilerplate:\n\n```rust\nuse vespera::{vespera, Serve};\n\n#[tokio::main]\nasync fn main() -> std::io::Result<()> {\n vespera!(docs_url = \"/docs\")\n .serve(\"0.0.0.0:3000\")\n .await\n}\n```\n\n`addr` accepts anything `tokio::net::ToSocketAddrs` takes — strings like `\"0.0.0.0:3000\"`, tuples like `([0, 0, 0, 0], 3000)`, or a `SocketAddr`.\n\n## export_app! Macro\n\nExport a Vespera app from a library crate so it can be merged into a parent app:\n\n```rust\n// In the child crate's src/lib.rs\nmod routes;\n\n// Scans \"routes\" folder by default\nvespera::export_app!(MyApp);\n\n// Or with a custom directory\nvespera::export_app!(MyApp, dir = \"api\");\n```\n\nThis generates a struct with two associated items:\n- `MyApp::OPENAPI_SPEC: &'static str` — the OpenAPI JSON spec as a static string\n- `MyApp::router() -> Router` — a function returning the Axum router\n\nThe parent app merges it with `merge = [MyApp]` in `vespera!()`.\n","title":"vespera!

Drop a `pub async fn` with `#[vespera::route]` anywhere in `src/routes/` and Vespera discovers it at compile time — no manual router registration.\n\n```\nsrc/routes/\n├── mod.rs → /\n├── users.rs → /users\n├── posts.rs → /posts\n└── admin/\n ├── mod.rs → /admin\n └── stats.rs → /admin/stats\n```\n\nSee [File-Based Routing](/documentation/concept/concept-1) for the full rules.\n\n## Schema & OpenAPI Generation\n\nDerive `Schema` on any Rust type and Vespera includes it in the generated OpenAPI 3.1 spec.

Jobs are auto-discovered like routes — no extra registration needed.\n\n### Enable the Feature\n\n```toml\n[dependencies]\nvespera = { version = \"0.1\", features = [\"cron\"] }\n```\n\n### Define Jobs\n\nPlace `#[vespera::cron(\"...\")]` on any `pub async fn` with zero parameters. The function can live anywhere in your project:\n\n```rust\n// src/cron/cleanup.rs, src/tasks.rs, or even src/routes/users.rs — anywhere works\n#[vespera::cron(\"1/10 * * * * *\")]\npub async fn cleanup_sessions() {\n println!(\"Running cleanup every 10 seconds\");\n}\n\n#[vespera::cron(\"0 0 * * * *\")]\npub async fn hourly_report() {\n println!(\"Running hourly report\");\n}\n```\n\nNo extra config in `vespera!()` — jobs are discovered and started automatically:\n\n```rust\nlet app = vespera!(docs_url = \"/docs\");\n// Background scheduler starts when the app starts\n```\n\n### Cron Expression Format\n\nUses 6-field cron expressions (`sec min hour day month weekday`):\n\n| Expression | Schedule |\n|-----------|----------|\n| `0 */5 * * * *` | Every 5 minutes |\n| `0 0 * * * *` | Every hour |\n| `0 0 0 * * *` | Daily at midnight |\n| `1/10 * * * * *` | Every 10 seconds |\n| `0 30 9 * * Mon-Fri` | Weekdays at 9:30 AM |\n\n### Requirements\n\n- Functions must be `pub async fn`\n- Functions must take **no parameters** (no `State`, no extractors)\n- The `cron` feature must be enabled in `Cargo.toml`\n\n---\n\n## Multipart Form Data\n\n### Typed Multipart (Recommended)\n\nUse `TypedMultipart` for file uploads with a statically-known schema. Vespera generates `multipart/form-data` content type in OpenAPI and maps `FieldData` to `{ \"type\": \"string\", \"format\": \"binary\" }`:\n\n```rust\nuse vespera::multipart::{FieldData, TypedMultipart};\nuse vespera::{Multipart, Schema};\nuse tempfile::NamedTempFile;\n\n#[derive(Multipart, Schema)]\npub struct CreateUploadRequest {\n pub name: String,\n #[form_data(limit = \"10MiB\")]\n pub file: Option>,\n}\n\n#[vespera::route(post, tags = [\"uploads\"])]\npub async fn create_upload(\n TypedMultipart(req): TypedMultipart,\n) -> Json { ... }\n```\n\n### Raw Multipart (Untyped)\n\nFor dynamic fields not known at compile time, use Axum's built-in `Multipart` extractor. Vespera generates a generic `{ \"type\": \"object\" }` schema:\n\n```rust\nuse vespera::axum::extract::Multipart;\n\n#[vespera::route(post, tags = [\"uploads\"])]\npub async fn upload(mut multipart: Multipart) -> Json {\n while let Some(field) = multipart.next_field().await.unwrap() {\n let name = field.name().unwrap_or(\"unknown\").to_string();\n let data = field.bytes().await.unwrap();\n // Process each field dynamically...\n }\n Json(UploadResponse { success: true })\n}\n```\n\n---\n\n## Merging Multiple Vespera Apps\n\nCombine routes and OpenAPI specs from multiple crates at compile time.

    \n\nBinary streaming throughput (64 MiB payload, bidirectional):\n\n\n \n \n Chunk size\n Throughput\n \n \n \n \n 16 KiB\n ~10,408 MiB/s\n \n \n 64 KiB\n ~11,587 MiB/s\n \n \n 256 KiB\n ~14,458 MiB/s\n \n \n
    \n\nThe `direct_pooled` path completes a tiny `/health` round-trip in **2,349 ns/op** — **1.55× faster** than the pre-1.0.0 sync baseline (3,643 ns/op).\n\n## How It Works\n\n```\nsrc/routes/\n├── mod.rs → /\n├── users.rs → /users\n└── admin/\n └── stats.rs → /admin/stats\n```\n\n1. You place `pub async fn` handlers in `src/routes/` and annotate them with `#[vespera::route]`.\n2. The `vespera!()` macro scans the folder at compile time, discovers every handler, and builds an `axum::Router`.\n3. Types annotated with `#[derive(Schema)]` are extracted into OpenAPI component schemas automatically.\n4. The generated `openapi.json` and Swagger UI are served at the URLs you configure.\n\n## Get Started\n\nHead to [Installation](/documentation/installation) to add Vespera to your project in under five minutes.\n","title":"What is Vespera?","url":"/documentation/overview"},{"text":"# JNI / Java Integration\n\nVespera can embed your Axum router directly inside a Java/Spring application — no TCP socket, no JSON envelope overhead, raw bytes from end to end.\n\nThe `vespera-bridge` library (`kr.devfive:vespera-bridge`) provides a Spring Boot autoconfiguration that wires up a catch-all `VesperaProxyController`. Every HTTP request Spring receives is forwarded to Rust through a length-prefixed binary wire format, and the response comes back the same way.\n\n## Why In-Process?\n\nA traditional microservice setup adds a full HTTP round-trip between Java and Rust. In-process JNI dispatch eliminates that entirely:\n\n- No TCP connection overhead\n- No JSON serialization of the envelope\n- Binary bodies (multipart, PDFs, images) travel as raw bytes — no base64\n- Measured latency for small requests: **~2,200 ns** with the `DIRECT` dispatch mode\n\n## Quick Navigation\n\n- [jni_app! & VesperaBridge](/documentation/theme/theme-1) — Rust setup, Java setup, native library loading\n- [Dispatch Modes & Wire Format](/documentation/theme/theme-2) — all seven dispatch methods, binary wire layout, `SmartDispatchModeResolver` defaults\n- [Streaming & Multi-App](/documentation/theme/theme-3) — streaming tuning, multi-app routing, virtual thread notes, 1.0.0 breaking changes\n\n## Two-Line Integration\n\n**Rust side:**\n\n```rust\npub fn create_app() -> vespera::axum::Router {\n vespera!(title = \"My API\")\n}\n\nvespera::jni_app!(create_app);\n```\n\n**Java side:**\n\n```java\n@SpringBootApplication\n@ComponentScan(basePackages = {\"com.example.app\", \"com.devfive.vespera.bridge\"})\npublic class MyApp {\n public static void main(String[] args) {\n VesperaBridge.init(\"my_rust_lib\");\n SpringApplication.run(MyApp.class, args);\n }\n}\n```\n\nThat's it. `VesperaProxyController` is autoconfigured and forwards every HTTP request to Rust. Zero controller code, zero `application.yml` config, zero extra imports beyond the Spring Boot starter.\n","title":"JNI / Java Integration","url":"/documentation/theme"},{"text":"# jni_app! & VesperaBridge\n\n## Rust Setup\n\n### 1. Enable the JNI Feature\n\n```toml\n[dependencies]\nvespera = { version = \"0.1\", features = [\"jni\"] }\n```\n\nThe `jni` feature implies `inprocess` — both are enabled automatically.\n\n### 2.

You write zero JNI code.\n\n### 3. Build as a cdylib\n\n```toml\n[lib]\ncrate-type = [\"cdylib\"]\n```\n\n```bash\ncargo build --release\n# Produces: target/release/libmy_rust_lib.so (Linux)\n# target/release/my_rust_lib.dll (Windows)\n# target/release/libmy_rust_lib.dylib (macOS)\n```\n\n---\n\n## Java Setup\n\n### Maven\n\n```xml\n\n kr.devfive\n vespera-bridge\n 1.0.0\n\n```\n\n### Gradle (Kotlin DSL)\n\n```kotlin\ndependencies {\n implementation(\"kr.devfive:vespera-bridge:1.0.0\")\n}\n```\n\n### Gradle Plugin (Recommended)\n\nThe `kr.devfive.vespera-bridge` Gradle plugin replaces ~22 lines of native-library-bundling boilerplate with a 5-line block:\n\n```kotlin\nplugins {\n id(\"kr.devfive.vespera-bridge\") version \"0.1.1\"\n}\n\nvespera {\n crateName.set(\"my_rust_lib\")\n cargoRoot.set(rootProject.layout.projectDirectory.dir(\"../..\"))\n bridgeVersion.set(\"1.0.0\")\n}\n```\n\nThe plugin auto-wires `bundleNativeLib` (cdylib → `resources/native/-/`), the `processResources` dependency, and the `vespera-bridge` implementation dependency.\n\n### Spring Boot Application\n\n```java\n@SpringBootApplication\n@ComponentScan(basePackages = {\"com.example.app\", \"com.devfive.vespera.bridge\"})\npublic class MyApp {\n public static void main(String[] args) {\n VesperaBridge.init(\"my_rust_lib\"); // loads cdylib (bundled or system path)\n SpringApplication.run(MyApp.class, args);\n }\n}\n```\n\n`VesperaProxyController` is autoconfigured via Spring Boot's `AutoConfiguration.imports`. It registers a `@RequestMapping(\"/**\")` catch-all that forwards every HTTP request to Rust. The routes published in Vespera's generated `openapi.json` are reachable at the same URLs through Spring.\n\n---\n\n## Native Library Loading\n\n`VesperaBridge.init(\"crateName\")` tries two paths in order:\n\n1. **Bundled** — looks up `native/{os}-{arch}/{libname}` inside the running JAR's classpath. If found, the file is extracted to a temp file (auto-deleted on JVM exit) and loaded via `System.load`.\n2. **Fallback** — `System.loadLibrary(\"crateName\")` searches `java.library.path`.\n\nSupported platform triples: `linux-x86_64`, `linux-aarch64`, `macos-x86_64`, `macos-aarch64`, `windows-x86_64`.\n\nPlace the cdylib at `src/main/resources/native/{os}-{arch}/` to bundle it inside the JAR for single-file deployment.\n\n---\n\n## Zero-Config Defaults\n\nOut of the box the autoconfigure module wires up:\n\n| Concern | Default | Override |\n|---------|---------|----------|\n| App selection | Read `X-Vespera-App` request header; absent → default app | Property `vespera.bridge.app-header`, or custom `AppNameResolver` bean |\n| Dispatch mode | `SmartDispatchModeResolver` since 1.0.0 — `DIRECT` for small/bodyless idempotent, `SYNC` for small non-idempotent, `BIDIRECTIONAL_STREAMING` for the rest | Property `vespera.bridge.dispatch-mode: bidirectional-streaming`, or custom `DispatchModeResolver` bean |\n| URL pattern | `@RequestMapping(\"/**\")` catch-all | Set `vespera.bridge.controller-enabled: false` and supply your own controller |\n\n---\n\n## Customization\n\n### Tweak via application.yml\n\n```yaml\nvespera:\n bridge:\n app-header: X-My-App # change the header that selects the app\n controller-enabled: true # set false to disable the proxy controller\n```\n\n### Custom App-Selection Strategy\n\n```java\n@Bean\npublic AppNameResolver myAppResolver() {\n return request -> {\n String uri = request.getRequestURI();\n if (uri.startsWith(\"/admin/\")) return \"admin\";\n if (uri.startsWith(\"/public/\")) return \"public\";\n return null; // default app\n };\n}\n```\n\nSpring's `@ConditionalOnMissingBean` automatically disables `HeaderAppNameResolver` when you supply your own bean.\n\n### Custom Dispatch-Mode Policy\n\n```java\n@Bean\npublic DispatchModeResolver myModeResolver() {\n return request -> {\n long contentLength = request.getContentLengthLong();\n if (contentLength >= 0 && contentLength < 4096\n && \"application/json\".equals(request.getContentType())) {\n return DispatchMode.SYNC;\n }\n return DispatchMode.BIDIRECTIONAL_STREAMING;\n };\n}\n```\n\n### BYO Controller\n\n```yaml\nvespera:\n bridge:\n controller-enabled: false\n```\n\n```java\n@RestController\npublic class MyController {\n @PostMapping(\"/api/admin/{path}\")\n public ResponseEntity adminRoute(@PathVariable String path, @RequestBody byte[] body) {\n byte[] wire = VesperaBridge.encodeRequest(\n \"admin\", \"POST\", \"/\" + path, null,\n Map.of(\"content-type\", \"application/json\"), body);\n byte[] resp = VesperaBridge.dispatchBytes(wire);\n DecodedResponse d = VesperaBridge.decodeResponse(resp);\n return ResponseEntity.status(d.status()).body(d.bodyBytes());\n }\n}\n```\n","title":"jni_app! & VesperaBridge","url":"/documentation/theme/theme-1"},{"text":"# Dispatch Modes & Wire Format\n\n## Binary Wire Format\n\nBoth request and response use the same length-prefixed layout:\n\n```\nbytes 0..4 : u32 BE = header_json byte length N\nbytes 4..4+N : UTF-8 JSON\n (request) { \"v\":1, \"method\", \"path\",\n \"query\"?, \"headers\"?

    \n\n### Choosing a Mode\n\n- Small JSON RPC, single request/response → `dispatchBytes`\n- Hot small/bounded payloads where JNI copy overhead matters → `dispatchDirect` / `dispatchDirectPooled`\n- Async I/O coordination (parallel Java requests, non-blocking) → `dispatchAsync` + `CompletableFuture`\n- Large download / streaming response (video, PDF, SSE) → `dispatchStreaming` + `OutputStream`\n- Large upload + large download (file transfer, video transcoding) → `dispatchFullStreaming` + `InputStream` + `OutputStream`\n- The `*WithHeader` variants let Spring-style controllers commit status/headers before the first body byte is written\n\n## SmartDispatchModeResolver (Default since 1.0.0)\n\nThe autoconfigured default since vespera-bridge 1.0.0 picks the cheapest safe path per request. Measured on a `GET /health` round-trip through the real JNI boundary:\n\n| Request shape | Mode | ns / round-trip |\n|---------------|------|-----------------|\n| Small/bodyless + idempotent (GET/HEAD/PUT/DELETE/OPTIONS, ≤ 256 KiB) | `DIRECT` | ~2,200 |\n| Small (≤ 256 KiB Content-Length) + non-idempotent (POST/PATCH) | `SYNC` | ~3,200 |\n| Large or unknown-length body | `BIDIRECTIONAL_STREAMING` | ~24,100 |\n\nTrade-offs:\n- **DIRECT** writes the wire response straight into a pooled per-thread direct `ByteBuffer` (64 KiB → `vespera.direct.maxBufferBytes`, default 4 MiB). Responses larger than the pooled buffer trigger a single retry that **re-runs the Rust handler** — which is why DIRECT is gated on idempotent methods only.\n- **SYNC** fully buffers the response on the JVM heap. The 256 KiB request-size gate keeps the response size reasonable for JSON-RPC-shaped traffic.\n- **BIDIRECTIONAL_STREAMING** is unchanged for large/unknown-length bodies — multi-GB upload + multi-GB download runs chunk-bounded, ~32 KiB resident each side.\n\nRestore the pre-1.0.0 default (every request that may carry a body streams both ways, ~24 µs uniform):\n\n```yaml\nvespera:\n bridge:\n dispatch-mode: bidirectional-streaming\n```\n\n## Direct Buffer Dispatch\n\n`dispatchDirect(ByteBuffer in, int inLen, ByteBuffer out)` eliminates the two JNI `GetByteArrayRegion`/`SetByteArrayRegion` copies that `dispatchBytes` pays. The response is streamed straight into the out buffer — no intermediate `Vec`. Measured at **1.4–3.4× per round-trip** versus `dispatchBytes` depending on payload size.\n\nContract:\n- Both buffers MUST be direct (`ByteBuffer.allocateDirect`); heap buffers are rejected with `IllegalArgumentException`\n- The request is read from absolute offsets `in[0..inLen]` — the buffer's position/limit are ignored; `inLen` is authoritative\n- Return `>= 0`: a complete wire response occupies `out[0..n]`\n- Return `< 0`: `-(requiredSize)` — the response did not fit; **retrying re-runs the Rust handler**, so only retry idempotent requests\n- `Integer.MIN_VALUE`: response exceeds 2 GiB\n\n`dispatchDirectPooled(byte[] wireRequest, boolean retryOnOverflow)` wraps the raw call with per-thread reusable direct buffers (64 KiB initial, doubling up to `vespera.direct.maxBufferBytes`, default 4 MiB).\n\n## Direct API (Without the Proxy Controller)\n\n```java\nimport com.devfive.vespera.bridge.VesperaBridge;\nimport com.devfive.vespera.bridge.VesperaBridge.DecodedResponse;\n\n// 1.

Encode a request\nbyte[] wireRequest = VesperaBridge.encodeRequest(\n \"POST\",\n \"/documents/validate\",\n /* query */ null,\n Map.of(\"content-type\", \"application/json\"),\n \"{\\\"title\\\":\\\"…\\\"}\".getBytes(StandardCharsets.UTF_8));\n\n// 3.

The owned `byte[]` materialisation moved to `DecodedResponse.bodyBytes()`. Callers that previously used `body()` as `byte[]` must switch to `bodyBytes()`.\n\n## Async Dispatch\n\n```java\nCompletableFuture future = VesperaBridge.dispatch(wireRequest);\n\nfuture.thenAccept(wireResponse -> {\n DecodedResponse resp = VesperaBridge.decodeResponse(wireResponse);\n System.out.println(\"Status: \" + resp.status());\n});\n```\n\nThe future is **always** completed with a valid wire response, even on Rust panics or JNI conversion failures. You will never see a dangling future.\n\n## Streaming Dispatch\n\n```java\nbyte[] wireRequest = VesperaBridge.encodeRequest(\n \"GET\", \"/files/large.pdf\", null, Map.of(), new byte[0]);\n\ntry (ByteArrayOutputStream sink = new ByteArrayOutputStream()) {\n byte[] headerOnly = VesperaBridge.dispatchStreaming(wireRequest, sink);\n DecodedResponse meta = VesperaBridge.decodeResponse(headerOnly);\n System.out.println(\"Status: \" + meta.status());\n System.out.println(\"Body size: \" + sink.size());\n}\n```\n\n## Bidirectional Streaming\n\n```java\ntry (InputStream upload = Files.newInputStream(Path.of(\"huge.mp4\"));\n OutputStream download = Files.newOutputStream(Path.of(\"transcoded.mp4\"))) {\n\n byte[] wireHeader = VesperaBridge.encodeRequestHeader(\n \"POST\", \"/transcode\", null,\n Map.of(\"content-type\", \"video/mp4\"));\n\n byte[] respHeader = VesperaBridge.dispatchFullStreaming(\n wireHeader, upload, download);\n\n DecodedResponse meta = VesperaBridge.decodeResponse(respHeader);\n System.out.println(\"Status: \" + meta.status());\n}\n```\n\nA 1 GiB upload paired with a 1 GiB download runs in low-single-digit MiB resident memory on each side. Backpressure is enforced naturally — if Axum reads slowly, `InputStream.read()` blocks on the bounded channel.\n","title":"Dispatch Modes & Wire Format","url":"/documentation/theme/theme-2"},{"text":"# Streaming & Multi-App\n\n## Streaming Tuning\n\nBoth streaming knobs are fixed for the process lifetime once the first dispatch runs. Configuration precedence (first hit wins):\n\n1. **Programmatic setter** — `VesperaBridge.configureStreaming(chunkBytes, channelCapacity)` (call before or after `init`)\n2. **System properties** — `vespera.streaming.chunkBytes`, `vespera.streaming.channelCapacity`\n3. **Environment variables** — `VESPERA_STREAMING_CHUNK_BYTES`, `VESPERA_STREAMING_CHANNEL_CAPACITY`\n4. **Built-in defaults** — 64 KiB chunk size, 16 channel slots\n\n| Setting | System property | Env var | Default | Range |\n|---------|----------------|---------|---------|-------|\n| Chunk buffer size | `vespera.streaming.chunkBytes` | `VESPERA_STREAMING_CHUNK_BYTES` | 64 KiB | 4 KiB – 8 MiB |\n| Request channel slots | `vespera.streaming.channelCapacity` | `VESPERA_STREAMING_CHANNEL_CAPACITY` | 16 | 1 – 1024 |\n| Tokio worker threads | `vespera.runtime.workerThreads` | `VESPERA_RUNTIME_WORKERS` | logical CPUs | 1 – 1024 |\n\n### Java API\n\nCall before `VesperaBridge.init(...)` for guaranteed precedence:\n\n```java\nVesperaBridge.configureStreaming(\n 131072, // chunkBytes: 128 KiB (clamped to 4 KiB – 8 MiB)\n 32 // channelCapacity: 32 slots (clamped to 1 – 1024)\n);\nVesperaBridge.init(\"my_rust_lib\");\n```\n\nWhen called before `init()`, values are stored as pending and applied immediately after the native library loads — before any dispatch can occur. This ensures the programmatic setter beats system properties and environment variables.\n\nThrows `IllegalArgumentException` if `chunkBytes` is outside `[4096, 8388608]` or `channelCapacity` is outside `[1, 1024]`.\n\n### System Properties\n\n```bash\njava -Dvespera.streaming.chunkBytes=131072 \\\n -Dvespera.streaming.channelCapacity=32 \\\n -jar app.jar\n```\n\n### Environment Variables\n\n```bash\nexport VESPERA_STREAMING_CHUNK_BYTES=131072\nexport VESPERA_STREAMING_CHANNEL_CAPACITY=32\njava -jar app.jar\n```\n\n### Tuning Tips\n\n- Larger chunks reduce the per-chunk JNI crossing cost (one `SetByteArrayRegion` + one `OutputStream.write` per chunk) at the price of per-stream memory. 256 KiB is a reasonable ceiling for throughput-oriented deployments.\n- The Tokio worker-thread knob caps Rust's shared runtime — useful when the JVM's own pools (Tomcat request threads, virtual-thread carriers) compete with Tokio for the same cores, or when a container CPU limit is lower than the host's logical CPU count.\n\n---\n\n## Multi-App Routing\n\nMulti-app routing is primarily a feature for external-dispatcher scenarios — JNI (Java host picks app per request via header), WebAssembly bridge, C FFI, or any in-process embedding where the host distinguishes between multiple independent Vespera API surfaces.\n\n### Rust Side\n\n```rust\npub fn create_app() -> axum::Router { vespera!(title = \"Default\") }\npub fn admin_app() -> axum::Router { vespera!(dir = \"admin_routes\", title = \"Admin\") }\npub fn public_app() -> axum::Router { vespera!(dir = \"public_routes\", title = \"Public\") }\n\nvespera::jni_apps! {\n \"_default\" => create_app,\n \"admin\" => admin_app,\n \"public\" => public_app,\n}\n```\n\n`jni_apps!` is the primary multi-app API. `jni_app!(create_app)` is syntactic sugar for a single default app.\n\n### Java Side\n\nThe default `HeaderAppNameResolver` selects an app per request via the `X-Vespera-App` header:\n\n```bash\n# Default app (no header)\ncurl http://localhost:8080/health\n\n# Admin app\ncurl -H \"X-Vespera-App: admin\" http://localhost:8080/dashboard\n\n# Public app\ncurl -H \"X-Vespera-App: public\" http://localhost:8080/info\n```\n\nEach app's URLs are independent — the same `/users` path can mean different things in `admin` vs `public` apps. Unknown app names return `404`; invalid app names (special characters, > 64 bytes) return `400`.\n\n### Custom App-Selection Strategy\n\n```java\n@Bean\npublic AppNameResolver myAppResolver() {\n // App name from the first path segment:\n // /admin/dashboard → app \"admin\", path \"/dashboard\"\n // /public/info → app \"public\", path \"/info\"\n return request -> {\n String uri = request.getRequestURI();\n if (uri.startsWith(\"/admin/\")) return \"admin\";\n if (uri.startsWith(\"/public/\")) return \"public\";\n return null; // default app\n };\n}\n```\n\n---\n\n## Virtual Thread (Project Loom) Limitation\n\nThe pooled direct-buffer methods (`dispatchDirectPooled`) use `ThreadLocal` to maintain per-thread reusable buffers. In Java 21+, `ThreadLocal` binds to the **virtual thread** (not the carrier thread) — so in a virtual-thread-per-request server, each virtual thread allocates a fresh direct buffer and loses all pooling benefit. Direct memory accumulates until the virtual thread is garbage-collected, potentially causing memory pressure under high concurrency.\n\n**Recommendations for virtual-thread deployments:**\n\n- Set `vespera.bridge.dispatch-mode=bidirectional-streaming` to opt out of the smart default, so `DIRECT` is never chosen by the autoconfigured resolver.\n- Or use `dispatchBytes`, `dispatchStreaming`, or `dispatchFullStreaming` directly instead of the pooled direct variants.\n- Or run dispatch on a bounded platform-thread executor (e.g. a `ForkJoinPool` with a fixed parallelism cap).\n- Or lower `vespera.direct.maxBufferBytes` to reduce per-thread allocation size.\n\n`DispatchMode.BIDIRECTIONAL_STREAMING` is safe for virtual threads and handles all payload sizes without pooling.\n\n---\n\n## 1.0.0 Breaking Changes\n\n### 1. Default DispatchModeResolver Flipped to SmartDispatchModeResolver\n\nPre-1.0.0 the autoconfigured default was `BidirectionalStreamingDispatchModeResolver` — every request that may carry a body streamed both ways, ~24.1 µs per round-trip uniform. Since 1.0.0 the default is `SmartDispatchModeResolver`.\n\n| Request shape | Pre-1.0.0 mode | 1.0.0+ mode |\n|---------------|----------------|-------------|\n| Small/bodyless idempotent (GET/HEAD/PUT/DELETE/OPTIONS, ≤ 256 KiB CL or no CL) | `STREAMING` / `BIDIRECTIONAL_STREAMING` | `DIRECT` |\n| Small non-idempotent (POST/PATCH, ≤ 256 KiB CL) | `BIDIRECTIONAL_STREAMING` | `SYNC` |\n| Large or unknown-length body | `BIDIRECTIONAL_STREAMING` | `BIDIRECTIONAL_STREAMING` |\n\nOpt out (restore the pre-1.0.0 default):\n\n```yaml\nvespera:\n bridge:\n dispatch-mode: bidirectional-streaming\n```\n\nOr register a custom `DispatchModeResolver` bean — `@ConditionalOnMissingBean` ensures it wins over both the property and the autoconfigured default.\n\n### 2. DecodedResponse.body() Returns ByteBuffer\n\n`DecodedResponse.body()` now returns a read-only `java.nio.ByteBuffer` (zero-copy view over the wire bytes). The owned `byte[]` materialisation moved to `DecodedResponse.bodyBytes()`.\n\n```java\n// Before 1.0.0\nbyte[] body = resp.body();\n\n// After 1.0.0\nbyte[] body = resp.bodyBytes(); // owned copy\nByteBuffer view = resp.body(); // zero-copy view\n```\n\nCallers that previously consumed `body()` as `byte[]` must switch to `bodyBytes()`.\n\n---\n\n## Migrating from the JSON-Envelope Bridge (≤ 0.0.13)\n\nThe pre-0.0.14 bridge used `dispatch(String) → String` with base64-encoded binary bodies.\n\n| Before | After |\n|--------|-------|\n| `VesperaBridge.dispatch(json)` | `encodeRequest(...)` → `dispatchBytes(...)` → `decodeResponse(...)` |\n| `body_bytes_b64` field on the response JSON | raw body bytes after the wire header (no base64) |\n| ~33% size overhead on binary bodies | zero overhead |\n\nExisting users of `VesperaProxyController` need no code change — the controller was rewritten to the new wire path internally. Direct callers of `VesperaBridge.dispatch(String)` must update; the old method was removed in 0.0.14.\n","title":"Streaming & Multi-App","url":"/documentation/theme/theme-3"}] \ No newline at end of file diff --git a/apps/landing/src/app/documentation/[...name]/api.api-1.mdx b/apps/landing/src/app/documentation/[...name]/api.api-1.mdx index 7b4d68d7..eb18a44a 100644 --- a/apps/landing/src/app/documentation/[...name]/api.api-1.mdx +++ b/apps/landing/src/app/documentation/[...name]/api.api-1.mdx @@ -1 +1,133 @@ -empty \ No newline at end of file +# vespera!

It transforms all your styles at build time, completely eliminating runtime overhead while providing full CSS-in-JS syntax coverage. - -### The Problem with Traditional CSS-in-JS - -Traditional CSS-in-JS solutions force you to choose between: - -- **Developer Experience**: Intuitive APIs, co-located styles, dynamic theming -- **Performance**: No runtime overhead, fast page loads, optimal Core Web Vitals - -Libraries like styled-components and Emotion offer great DX but execute JavaScript at runtime to generate styles. Zero-runtime alternatives like Vanilla Extract sacrifice some flexibility for performance. - -### The Devup UI Solution - -Devup UI eliminates this trade-off entirely. Our Rust-powered preprocessor analyzes your code at build time and handles every CSS-in-JS pattern: - -- **Variables** — Dynamic values become CSS custom properties -- **Conditionals** — Ternary expressions are statically analyzed -- **Responsive Arrays** — Breakpoint-based styles are pre-generated -- **Pseudo Selectors** — `_hover`, `_focus`, `_active` work seamlessly -- **Themes** — Type-safe theme tokens with zero-cost switching - -### Key Advantages - - - - - Feature - Devup UI - styled-components - Emotion - Vanilla Extract - - - - - Zero Runtime - Yes - No - No - Yes - - - Dynamic Values - Yes - Yes - Yes - Limited - - - Full Syntax Coverage - Yes - Yes - Yes - No - - - Type-Safe Themes - Yes - Limited - Limited - Yes - - - Build Performance - Fastest - N/A - N/A - Fast - - -

In Java 21+, `ThreadLocal` binds to the **virtual thread** (not the carrier thread) — so in a virtual-thread-per-request server, each virtual thread allocates a fresh direct buffer and loses all pooling benefit. Direct memory accumulates until the virtual thread is garbage-collected, potentially causing memory pressure under high concurrency. + +**Recommendations for virtual-thread deployments:** + +- Set `vespera.bridge.dispatch-mode=bidirectional-streaming` to opt out of the smart default, so `DIRECT` is never chosen by the autoconfigured resolver. +- Or use `dispatchBytes`, `dispatchStreaming`, or `dispatchFullStreaming` directly instead of the pooled direct variants. +- Or run dispatch on a bounded platform-thread executor (e.g. a `ForkJoinPool` with a fixed parallelism cap). +- Or lower `vespera.direct.maxBufferBytes` to reduce per-thread allocation size. + +`DispatchMode.BIDIRECTIONAL_STREAMING` is safe for virtual threads and handles all payload sizes without pooling. + +--- + +## 1.0.0 Breaking Changes + +### 1.

    \n\n## JNI Performance Numbers\n\nWhen embedding Vespera inside a Java/Spring application via JNI, the `SmartDispatchModeResolver` (default since vespera-bridge 1.0.0) picks the cheapest safe path per request. Measured on a `GET /health` round-trip through the real JNI boundary (AMD Ryzen 9 9950X, Java 21, Windows 11):\n\n\n \n \n Request shape\n Mode\n ns / round-trip\n \n \n \n \n Small/bodyless + idempotent (GET/HEAD/PUT/DELETE/OPTIONS, ≤ 256 KiB)\n `DIRECT` (pooled direct buffers)\n ~2,200 ns\n \n \n Small (≤ 256 KiB) + non-idempotent (POST/PATCH)\n `SYNC` (heap-buffered)\n ~3,200 ns\n \n \n Large or unknown-length body\n `BIDIRECTIONAL_STREAMING`\n ~24,100 ns\n \n \n
    \n\nBinary streaming throughput (64 MiB payload, bidirectional):\n\n\n \n \n Chunk size\n Throughput\n \n \n \n \n 16 KiB\n ~10,408 MiB/s\n \n \n 64 KiB\n ~11,587 MiB/s\n \n \n 256 KiB\n ~14,458 MiB/s\n \n \n
    \n\nThe `direct_pooled` path completes a tiny `/health` round-trip in **2,349 ns/op** — **1.55× faster** than the pre-1.0.0 sync baseline (3,643 ns/op).\n\n## How It Works\n\n```\nsrc/routes/\n├── mod.rs → /\n├── users.rs → /users\n└── admin/\n └── stats.rs → /admin/stats\n```\n\n1. You place `pub async fn` handlers in `src/routes/` and annotate them with `#[vespera::route]`.\n2. The `vespera!()` macro scans the folder at compile time, discovers every handler, and builds an `axum::Router`.\n3. Types annotated with `#[derive(Schema)]` are extracted into OpenAPI component schemas automatically.\n4. The generated `openapi.json` and Swagger UI are served at the URLs you configure.\n\n## Get Started\n\nHead to [Installation](/documentation/installation) to add Vespera to your project in under five minutes.\n","title":"What is Vespera?","url":"/documentation/overview"},{"text":"# JNI / Java Integration\n\nVespera can embed your Axum router directly inside a Java/Spring application — no TCP socket, no JSON envelope overhead, raw bytes from end to end.\n\nThe `vespera-bridge` library (`kr.devfive:vespera-bridge`) provides a Spring Boot autoconfiguration that wires up a catch-all `VesperaProxyController`. Every HTTP request Spring receives is forwarded to Rust through a length-prefixed binary wire format, and the response comes back the same way.\n\n## Why In-Process?\n\nA traditional microservice setup adds a full HTTP round-trip between Java and Rust. In-process JNI dispatch eliminates that entirely:\n\n- No TCP connection overhead\n- No JSON serialization of the envelope\n- Binary bodies (multipart, PDFs, images) travel as raw bytes — no base64\n- Measured latency for small requests: **~2,200 ns** with the `DIRECT` dispatch mode\n\n## Quick Navigation\n\n- [jni_app! & VesperaBridge](/documentation/theme/theme-1) — Rust setup, Java setup, native library loading\n- [Dispatch Modes & Wire Format](/documentation/theme/theme-2) — all seven dispatch methods, binary wire layout, `SmartDispatchModeResolver` defaults\n- [Streaming & Multi-App](/documentation/theme/theme-3) — streaming tuning, multi-app routing, virtual thread notes, 1.0.0 breaking changes\n\n## Two-Line Integration\n\n**Rust side:**\n\n```rust\npub fn create_app() -> vespera::axum::Router {\n vespera!(title = \"My API\")\n}\n\nvespera::jni_app!(create_app);\n```\n\n**Java side:**\n\n```java\n@SpringBootApplication\n@ComponentScan(basePackages = {\"com.example.app\", \"com.devfive.vespera.bridge\"})\npublic class MyApp {\n public static void main(String[] args) {\n VesperaBridge.init(\"my_rust_lib\");\n SpringApplication.run(MyApp.class, args);\n }\n}\n```\n\nThat's it. `VesperaProxyController` is autoconfigured and forwards every HTTP request to Rust. Zero controller code, zero `application.yml` config, zero extra imports beyond the Spring Boot starter.\n","title":"JNI / Java Integration","url":"/documentation/theme"},{"text":"# jni_app! & VesperaBridge\n\n## Rust Setup\n\n### 1. Enable the JNI Feature\n\n```toml\n[dependencies]\nvespera = { version = \"0.1\", features = [\"jni\"] }\n```\n\nThe `jni` feature implies `inprocess` — both are enabled automatically.\n\n### 2. Export Your App\n\nIn your cdylib crate's `src/lib.rs`:\n\n```rust\nuse vespera::{axum, vespera};\n\npub fn create_app() -> axum::Router {\n vespera!(title = \"My API\", version = \"1.0.0\")\n}\n\n// Single app — generates JNI_OnLoad and the dispatch symbol\nvespera::jni_app!(create_app);\n```\n\n`jni_app!` generates all JNI boilerplate: `JNI_OnLoad`, the Tokio runtime, and the seven dispatch symbols. You write zero JNI code.\n\n### 3. Build as a cdylib\n\n```toml\n[lib]\ncrate-type = [\"cdylib\"]\n```\n\n```bash\ncargo build --release\n# Produces: target/release/libmy_rust_lib.so (Linux)\n# target/release/my_rust_lib.dll (Windows)\n# target/release/libmy_rust_lib.dylib (macOS)\n```\n\n---\n\n## Java Setup\n\n### Maven\n\n```xml\n\n kr.devfive\n vespera-bridge\n 1.0.0\n\n```\n\n### Gradle (Kotlin DSL)\n\n```kotlin\ndependencies {\n implementation(\"kr.devfive:vespera-bridge:1.0.0\")\n}\n```\n\n### Gradle Plugin (Recommended)\n\nThe `kr.devfive.vespera-bridge` Gradle plugin replaces ~22 lines of native-library-bundling boilerplate with a 5-line block:\n\n```kotlin\nplugins {\n id(\"kr.devfive.vespera-bridge\") version \"0.1.1\"\n}\n\nvespera {\n crateName.set(\"my_rust_lib\")\n cargoRoot.set(rootProject.layout.projectDirectory.dir(\"../..\"))\n bridgeVersion.set(\"1.0.0\")\n}\n```\n\nThe plugin auto-wires `bundleNativeLib` (cdylib → `resources/native/-/`), the `processResources` dependency, and the `vespera-bridge` implementation dependency.\n\n### Spring Boot Application\n\n```java\n@SpringBootApplication\n@ComponentScan(basePackages = {\"com.example.app\", \"com.devfive.vespera.bridge\"})\npublic class MyApp {\n public static void main(String[] args) {\n VesperaBridge.init(\"my_rust_lib\"); // loads cdylib (bundled or system path)\n SpringApplication.run(MyApp.class, args);\n }\n}\n```\n\n`VesperaProxyController` is autoconfigured via Spring Boot's `AutoConfiguration.imports`. It registers a `@RequestMapping(\"/**\")` catch-all that forwards every HTTP request to Rust. The routes published in Vespera's generated `openapi.json` are reachable at the same URLs through Spring.\n\n---\n\n## Native Library Loading\n\n`VesperaBridge.init(\"crateName\")` tries two paths in order:\n\n1. **Bundled** — looks up `native/{os}-{arch}/{libname}` inside the running JAR's classpath. If found, the file is extracted to a temp file (auto-deleted on JVM exit) and loaded via `System.load`.\n2. **Fallback** — `System.loadLibrary(\"crateName\")` searches `java.library.path`.\n\nSupported platform triples: `linux-x86_64`, `linux-aarch64`, `macos-x86_64`, `macos-aarch64`, `windows-x86_64`.\n\nPlace the cdylib at `src/main/resources/native/{os}-{arch}/` to bundle it inside the JAR for single-file deployment.\n\n---\n\n## Zero-Config Defaults\n\nOut of the box the autoconfigure module wires up:\n\n| Concern | Default | Override |\n|---------|---------|----------|\n| App selection | Read `X-Vespera-App` request header; absent → default app | Property `vespera.bridge.app-header`, or custom `AppNameResolver` bean |\n| Dispatch mode | `SmartDispatchModeResolver` since 1.0.0 — `DIRECT` for small/bodyless idempotent, `SYNC` for small non-idempotent, `BIDIRECTIONAL_STREAMING` for the rest | Property `vespera.bridge.dispatch-mode: bidirectional-streaming`, or custom `DispatchModeResolver` bean |\n| URL pattern | `@RequestMapping(\"/**\")` catch-all | Set `vespera.bridge.controller-enabled: false` and supply your own controller |\n\n---\n\n## Customization\n\n### Tweak via application.yml\n\n```yaml\nvespera:\n bridge:\n app-header: X-My-App # change the header that selects the app\n controller-enabled: true # set false to disable the proxy controller\n```\n\n### Custom App-Selection Strategy\n\n```java\n@Bean\npublic AppNameResolver myAppResolver() {\n return request -> {\n String uri = request.getRequestURI();\n if (uri.startsWith(\"/admin/\")) return \"admin\";\n if (uri.startsWith(\"/public/\")) return \"public\";\n return null; // default app\n };\n}\n```\n\nSpring's `@ConditionalOnMissingBean` automatically disables `HeaderAppNameResolver` when you supply your own bean.\n\n### Custom Dispatch-Mode Policy\n\n```java\n@Bean\npublic DispatchModeResolver myModeResolver() {\n return request -> {\n long contentLength = request.getContentLengthLong();\n if (contentLength >= 0 && contentLength < 4096\n && \"application/json\".equals(request.getContentType())) {\n return DispatchMode.SYNC;\n }\n return DispatchMode.BIDIRECTIONAL_STREAMING;\n };\n}\n```\n\n### BYO Controller\n\n```yaml\nvespera:\n bridge:\n controller-enabled: false\n```\n\n```java\n@RestController\npublic class MyController {\n @PostMapping(\"/api/admin/{path}\")\n public ResponseEntity adminRoute(@PathVariable String path, @RequestBody byte[] body) {\n byte[] wire = VesperaBridge.encodeRequest(\n \"admin\", \"POST\", \"/\" + path, null,\n Map.of(\"content-type\", \"application/json\"), body);\n byte[] resp = VesperaBridge.dispatchBytes(wire);\n DecodedResponse d = VesperaBridge.decodeResponse(resp);\n return ResponseEntity.status(d.status()).body(d.bodyBytes());\n }\n}\n```\n","title":"jni_app! & VesperaBridge","url":"/documentation/theme/theme-1"},{"text":"# Dispatch Modes & Wire Format\n\n## Binary Wire Format\n\nBoth request and response use the same length-prefixed layout:\n\n```\nbytes 0..4 : u32 BE = header_json byte length N\nbytes 4..4+N : UTF-8 JSON\n (request) { \"v\":1, \"method\", \"path\",\n \"query\"?, \"headers\"?

    \n\n### Choosing a Mode\n\n- Small JSON RPC, single request/response → `dispatchBytes`\n- Hot small/bounded payloads where JNI copy overhead matters → `dispatchDirect` / `dispatchDirectPooled`\n- Async I/O coordination (parallel Java requests, non-blocking) → `dispatchAsync` + `CompletableFuture`\n- Large download / streaming response (video, PDF, SSE) → `dispatchStreaming` + `OutputStream`\n- Large upload + large download (file transfer, video transcoding) → `dispatchFullStreaming` + `InputStream` + `OutputStream`\n- The `*WithHeader` variants let Spring-style controllers commit status/headers before the first body byte is written\n\n## SmartDispatchModeResolver (Default since 1.0.0)\n\nThe autoconfigured default since vespera-bridge 1.0.0 picks the cheapest safe path per request. Measured on a `GET /health` round-trip through the real JNI boundary:\n\n| Request shape | Mode | ns / round-trip |\n|---------------|------|-----------------|\n| Small/bodyless + idempotent (GET/HEAD/PUT/DELETE/OPTIONS, ≤ 256 KiB) | `DIRECT` | ~2,200 |\n| Small (≤ 256 KiB Content-Length) + non-idempotent (POST/PATCH) | `SYNC` | ~3,200 |\n| Large or unknown-length body | `BIDIRECTIONAL_STREAMING` | ~24,100 |\n\nTrade-offs:\n- **DIRECT** writes the wire response straight into a pooled per-thread direct `ByteBuffer` (64 KiB → `vespera.direct.maxBufferBytes`, default 4 MiB). Responses larger than the pooled buffer trigger a single retry that **re-runs the Rust handler** — which is why DIRECT is gated on idempotent methods only.\n- **SYNC** fully buffers the response on the JVM heap. The 256 KiB request-size gate keeps the response size reasonable for JSON-RPC-shaped traffic.\n- **BIDIRECTIONAL_STREAMING** is unchanged for large/unknown-length bodies — multi-GB upload + multi-GB download runs chunk-bounded, ~32 KiB resident each side.\n\nRestore the pre-1.0.0 default (every request that may carry a body streams both ways, ~24 µs uniform):\n\n```yaml\nvespera:\n bridge:\n dispatch-mode: bidirectional-streaming\n```\n\n## Direct Buffer Dispatch\n\n`dispatchDirect(ByteBuffer in, int inLen, ByteBuffer out)` eliminates the two JNI `GetByteArrayRegion`/`SetByteArrayRegion` copies that `dispatchBytes` pays. The response is streamed straight into the out buffer — no intermediate `Vec`. Measured at **1.4–3.4× per round-trip** versus `dispatchBytes` depending on payload size.\n\nContract:\n- Both buffers MUST be direct (`ByteBuffer.allocateDirect`); heap buffers are rejected with `IllegalArgumentException`\n- The request is read from absolute offsets `in[0..inLen]` — the buffer's position/limit are ignored; `inLen` is authoritative\n- Return `>= 0`: a complete wire response occupies `out[0..n]`\n- Return `< 0`: `-(requiredSize)` — the response did not fit; **retrying re-runs the Rust handler**, so only retry idempotent requests\n- `Integer.MIN_VALUE`: response exceeds 2 GiB\n\n`dispatchDirectPooled(byte[] wireRequest, boolean retryOnOverflow)` wraps the raw call with per-thread reusable direct buffers (64 KiB initial, doubling up to `vespera.direct.maxBufferBytes`, default 4 MiB).\n\n## Direct API (Without the Proxy Controller)\n\n```java\nimport com.devfive.vespera.bridge.VesperaBridge;\nimport com.devfive.vespera.bridge.VesperaBridge.DecodedResponse;\n\n// 1.

The owned `byte[]` materialisation moved to `DecodedResponse.bodyBytes()`. Callers that previously used `body()` as `byte[]` must switch to `bodyBytes()`.\n\n## Async Dispatch\n\n```java\nCompletableFuture future = VesperaBridge.dispatch(wireRequest);\n\nfuture.thenAccept(wireResponse -> {\n DecodedResponse resp = VesperaBridge.decodeResponse(wireResponse);\n System.out.println(\"Status: \" + resp.status());\n});\n```\n\nThe future is **always** completed with a valid wire response, even on Rust panics or JNI conversion failures.

Configuration precedence (first hit wins):\n\n1. **Programmatic setter** — `VesperaBridge.configureStreaming(chunkBytes, channelCapacity)` (call before or after `init`)\n2. **System properties** — `vespera.streaming.chunkBytes`, `vespera.streaming.channelCapacity`\n3. **Environment variables** — `VESPERA_STREAMING_CHUNK_BYTES`, `VESPERA_STREAMING_CHANNEL_CAPACITY`\n4. **Built-in defaults** — 64 KiB chunk size, 16 channel slots\n\n| Setting | System property | Env var | Default | Range |\n|---------|----------------|---------|---------|-------|\n| Chunk buffer size | `vespera.streaming.chunkBytes` | `VESPERA_STREAMING_CHUNK_BYTES` | 64 KiB | 4 KiB – 8 MiB |\n| Request channel slots | `vespera.streaming.channelCapacity` | `VESPERA_STREAMING_CHANNEL_CAPACITY` | 16 | 1 – 1024 |\n| Tokio worker threads | `vespera.runtime.workerThreads` | `VESPERA_RUNTIME_WORKERS` | logical CPUs | 1 – 1024 |\n\n### Java API\n\nCall before `VesperaBridge.init(...)` for guaranteed precedence:\n\n```java\nVesperaBridge.configureStreaming(\n 131072, // chunkBytes: 128 KiB (clamped to 4 KiB – 8 MiB)\n 32 // channelCapacity: 32 slots (clamped to 1 – 1024)\n);\nVesperaBridge.init(\"my_rust_lib\");\n```\n\nWhen called before `init()`, values are stored as pending and applied immediately after the native library loads — before any dispatch can occur. This ensures the programmatic setter beats system properties and environment variables.\n\nThrows `IllegalArgumentException` if `chunkBytes` is outside `[4096, 8388608]` or `channelCapacity` is outside `[1, 1024]`.\n\n### System Properties\n\n```bash\njava -Dvespera.streaming.chunkBytes=131072 \\\n -Dvespera.streaming.channelCapacity=32 \\\n -jar app.jar\n```\n\n### Environment Variables\n\n```bash\nexport VESPERA_STREAMING_CHUNK_BYTES=131072\nexport VESPERA_STREAMING_CHANNEL_CAPACITY=32\njava -jar app.jar\n```\n\n### Tuning Tips\n\n- Larger chunks reduce the per-chunk JNI crossing cost (one `SetByteArrayRegion` + one `OutputStream.write` per chunk) at the price of per-stream memory. 256 KiB is a reasonable ceiling for throughput-oriented deployments.\n- The Tokio worker-thread knob caps Rust's shared runtime — useful when the JVM's own pools (Tomcat request threads, virtual-thread carriers) compete with Tokio for the same cores, or when a container CPU limit is lower than the host's logical CPU count.\n\n---\n\n## Multi-App Routing\n\nMulti-app routing is primarily a feature for external-dispatcher scenarios — JNI (Java host picks app per request via header), WebAssembly bridge, C FFI, or any in-process embedding where the host distinguishes between multiple independent Vespera API surfaces.\n\n### Rust Side\n\n```rust\npub fn create_app() -> axum::Router { vespera!(title = \"Default\") }\npub fn admin_app() -> axum::Router { vespera!(dir = \"admin_routes\", title = \"Admin\") }\npub fn public_app() -> axum::Router { vespera!(dir = \"public_routes\", title = \"Public\") }\n\nvespera::jni_apps! {\n \"_default\" => create_app,\n \"admin\" => admin_app,\n \"public\" => public_app,\n}\n```\n\n`jni_apps!` is the primary multi-app API. `jni_app!(create_app)` is syntactic sugar for a single default app.\n\n### Java Side\n\nThe default `HeaderAppNameResolver` selects an app per request via the `X-Vespera-App` header:\n\n```bash\n# Default app (no header)\ncurl http://localhost:8080/health\n\n# Admin app\ncurl -H \"X-Vespera-App: admin\" http://localhost:8080/dashboard\n\n# Public app\ncurl -H \"X-Vespera-App: public\" http://localhost:8080/info\n```\n\nEach app's URLs are independent — the same `/users` path can mean different things in `admin` vs `public` apps. Unknown app names return `404`; invalid app names (special characters, > 64 bytes) return `400`.\n\n### Custom App-Selection Strategy\n\n```java\n@Bean\npublic AppNameResolver myAppResolver() {\n // App name from the first path segment:\n // /admin/dashboard → app \"admin\", path \"/dashboard\"\n // /public/info → app \"public\", path \"/info\"\n return request -> {\n String uri = request.getRequestURI();\n if (uri.startsWith(\"/admin/\")) return \"admin\";\n if (uri.startsWith(\"/public/\")) return \"public\";\n return null; // default app\n };\n}\n```\n\n---\n\n## Virtual Thread (Project Loom) Limitation\n\nThe pooled direct-buffer methods (`dispatchDirectPooled`) use `ThreadLocal` to maintain per-thread reusable buffers. In Java 21+, `ThreadLocal` binds to the **virtual thread** (not the carrier thread) — so in a virtual-thread-per-request server, each virtual thread allocates a fresh direct buffer and loses all pooling benefit. Direct memory accumulates until the virtual thread is garbage-collected, potentially causing memory pressure under high concurrency.\n\n**Recommendations for virtual-thread deployments:**\n\n- Set `vespera.bridge.dispatch-mode=bidirectional-streaming` to opt out of the smart default, so `DIRECT` is never chosen by the autoconfigured resolver.\n- Or use `dispatchBytes`, `dispatchStreaming`, or `dispatchFullStreaming` directly instead of the pooled direct variants.\n- Or run dispatch on a bounded platform-thread executor (e.g. a `ForkJoinPool` with a fixed parallelism cap).\n- Or lower `vespera.direct.maxBufferBytes` to reduce per-thread allocation size.\n\n`DispatchMode.BIDIRECTIONAL_STREAMING` is safe for virtual threads and handles all payload sizes without pooling.\n\n---\n\n## 1.0.0 Breaking Changes\n\n### 1. Default DispatchModeResolver Flipped to SmartDispatchModeResolver\n\nPre-1.0.0 the autoconfigured default was `BidirectionalStreamingDispatchModeResolver` — every request that may carry a body streamed both ways, ~24.1 µs per round-trip uniform. Since 1.0.0 the default is `SmartDispatchModeResolver`.\n\n| Request shape | Pre-1.0.0 mode | 1.0.0+ mode |\n|---------------|----------------|-------------|\n| Small/bodyless idempotent (GET/HEAD/PUT/DELETE/OPTIONS, ≤ 256 KiB CL or no CL) | `STREAMING` / `BIDIRECTIONAL_STREAMING` | `DIRECT` |\n| Small non-idempotent (POST/PATCH, ≤ 256 KiB CL) | `BIDIRECTIONAL_STREAMING` | `SYNC` |\n| Large or unknown-length body | `BIDIRECTIONAL_STREAMING` | `BIDIRECTIONAL_STREAMING` |\n\nOpt out (restore the pre-1.0.0 default):\n\n```yaml\nvespera:\n bridge:\n dispatch-mode: bidirectional-streaming\n```\n\nOr register a custom `DispatchModeResolver` bean — `@ConditionalOnMissingBean` ensures it wins over both the property and the autoconfigured default.\n\n### 2. DecodedResponse.body() Returns ByteBuffer\n\n`DecodedResponse.body()` now returns a read-only `java.nio.ByteBuffer` (zero-copy view over the wire bytes). The owned `byte[]` materialisation moved to `DecodedResponse.bodyBytes()`.\n\n```java\n// Before 1.0.0\nbyte[] body = resp.body();\n\n// After 1.0.0\nbyte[] body = resp.bodyBytes(); // owned copy\nByteBuffer view = resp.body(); // zero-copy view\n```\n\nCallers that previously consumed `body()` as `byte[]` must switch to `bodyBytes()`.\n\n---\n\n## Migrating from the JSON-Envelope Bridge (≤ 0.0.13)\n\nThe pre-0.0.14 bridge used `dispatch(String) → String` with base64-encoded binary bodies.\n\n| Before | After |\n|--------|-------|\n| `VesperaBridge.dispatch(json)` | `encodeRequest(...)` → `dispatchBytes(...)` → `decodeResponse(...)` |\n| `body_bytes_b64` field on the response JSON | raw body bytes after the wire header (no base64) |\n| ~33% size overhead on binary bodies | zero overhead |\n\nExisting users of `VesperaProxyController` need no code change — the controller was rewritten to the new wire path internally. Direct callers of `VesperaBridge.dispatch(String)` must update; the old method was removed in 0.0.14.\n","title":"Streaming & Multi-App","url":"/documentation/theme/theme-3"}] \ No newline at end of file +[{"text":"# vespera!

    \n\n## JNI Performance Numbers\n\nWhen embedding Vespera inside a Java/Spring application via JNI, the `SmartDispatchModeResolver` (default since vespera-bridge 0.2.0) picks the cheapest safe path per request. Measured on a `GET /health` round-trip through the real JNI boundary (AMD Ryzen 9 9950X, Java 21, Windows 11):\n\n\n \n \n Request shape\n Mode\n ns / round-trip\n \n \n \n \n Small/bodyless + idempotent (GET/HEAD/PUT/DELETE/OPTIONS, ≤ 256 KiB)\n `DIRECT` (pooled direct buffers)\n ~2,200 ns\n \n \n Small (≤ 256 KiB) + non-idempotent (POST/PATCH)\n `SYNC` (heap-buffered)\n ~3,200 ns\n \n \n Large or unknown-length body\n `BIDIRECTIONAL_STREAMING`\n ~24,100 ns\n \n \n
    \n\nBinary streaming throughput (64 MiB payload, bidirectional):\n\n\n \n \n Chunk size\n Throughput\n \n \n \n \n 16 KiB\n ~10,408 MiB/s\n \n \n 64 KiB\n ~11,587 MiB/s\n \n \n 256 KiB\n ~14,458 MiB/s\n \n \n
    \n\nThe `direct_pooled` path completes a tiny `/health` round-trip in **2,349 ns/op** — **1.55× faster** than the pre-0.2.0 sync baseline (3,643 ns/op).\n\n## How It Works\n\n```\nsrc/routes/\n├── mod.rs → /\n├── users.rs → /users\n└── admin/\n └── stats.rs → /admin/stats\n```\n\n1. You place `pub async fn` handlers in `src/routes/` and annotate them with `#[vespera::route]`.\n2. The `vespera!()` macro scans the folder at compile time, discovers every handler, and builds an `axum::Router`.\n3. Types annotated with `#[derive(Schema)]` are extracted into OpenAPI component schemas automatically.\n4.

Every HTTP request Spring receives is forwarded to Rust through a length-prefixed binary wire format, and the response comes back the same way.\n\n## Why In-Process?\n\nA traditional microservice setup adds a full HTTP round-trip between Java and Rust. In-process JNI dispatch eliminates that entirely:\n\n- No TCP connection overhead\n- No JSON serialization of the envelope\n- Binary bodies (multipart, PDFs, images) travel as raw bytes — no base64\n- Measured latency for small requests: **~2,200 ns** with the `DIRECT` dispatch mode\n\n## Quick Navigation\n\n- [jni_app! & VesperaBridge](/documentation/theme/theme-1) — Rust setup, Java setup, native library loading\n- [Dispatch Modes & Wire Format](/documentation/theme/theme-2) — all seven dispatch methods, binary wire layout, `SmartDispatchModeResolver` defaults\n- [Streaming & Multi-App](/documentation/theme/theme-3) — streaming tuning, multi-app routing, virtual thread notes, 0.2.0 breaking changes\n\n## Two-Line Integration\n\n**Rust side:**\n\n```rust\npub fn create_app() -> vespera::axum::Router {\n vespera!(title = \"My API\")\n}\n\nvespera::jni_app!(create_app);\n```\n\n**Java side:**\n\n```java\n@SpringBootApplication\n@ComponentScan(basePackages = {\"com.example.app\", \"com.devfive.vespera.bridge\"})\npublic class MyApp {\n public static void main(String[] args) {\n VesperaBridge.init(\"my_rust_lib\");\n SpringApplication.run(MyApp.class, args);\n }\n}\n```\n\nThat's it. `VesperaProxyController` is autoconfigured and forwards every HTTP request to Rust.

Export Your App\n\nIn your cdylib crate's `src/lib.rs`:\n\n```rust\nuse vespera::{axum, vespera};\n\npub fn create_app() -> axum::Router {\n vespera!(title = \"My API\", version = \"1.0.0\")\n}\n\n// Single app — generates JNI_OnLoad and the dispatch symbol\nvespera::jni_app!(create_app);\n```\n\n`jni_app!` generates all JNI boilerplate: `JNI_OnLoad`, the Tokio runtime, and the seven dispatch symbols. You write zero JNI code.\n\n### 3. Build as a cdylib\n\n```toml\n[lib]\ncrate-type = [\"cdylib\"]\n```\n\n```bash\ncargo build --release\n# Produces: target/release/libmy_rust_lib.so (Linux)\n# target/release/my_rust_lib.dll (Windows)\n# target/release/libmy_rust_lib.dylib (macOS)\n```\n\n---\n\n## Java Setup\n\n### Maven\n\n```xml\n\n kr.devfive\n vespera-bridge\n 0.2.0\n\n```\n\n### Gradle (Kotlin DSL)\n\n```kotlin\ndependencies {\n implementation(\"kr.devfive:vespera-bridge:0.2.0\")\n}\n```\n\n### Gradle Plugin (Recommended)\n\nThe `kr.devfive.vespera-bridge` Gradle plugin replaces ~22 lines of native-library-bundling boilerplate with a 5-line block:\n\n```kotlin\nplugins {\n id(\"kr.devfive.vespera-bridge\") version \"0.1.1\"\n}\n\nvespera {\n crateName.set(\"my_rust_lib\")\n cargoRoot.set(rootProject.layout.projectDirectory.dir(\"../..\"))\n bridgeVersion.set(\"0.2.0\")\n}\n```\n\nThe plugin auto-wires `bundleNativeLib` (cdylib → `resources/native/-/`), the `processResources` dependency, and the `vespera-bridge` implementation dependency.\n\n### Spring Boot Application\n\n```java\n@SpringBootApplication\n@ComponentScan(basePackages = {\"com.example.app\", \"com.devfive.vespera.bridge\"})\npublic class MyApp {\n public static void main(String[] args) {\n VesperaBridge.init(\"my_rust_lib\"); // loads cdylib (bundled or system path)\n SpringApplication.run(MyApp.class, args);\n }\n}\n```\n\n`VesperaProxyController` is autoconfigured via Spring Boot's `AutoConfiguration.imports`. It registers a `@RequestMapping(\"/**\")` catch-all that forwards every HTTP request to Rust.

If found, the file is extracted to a temp file (auto-deleted on JVM exit) and loaded via `System.load`.\n2. **Fallback** — `System.loadLibrary(\"crateName\")` searches `java.library.path`.\n\nSupported platform triples: `linux-x86_64`, `linux-aarch64`, `macos-x86_64`, `macos-aarch64`, `windows-x86_64`.\n\nPlace the cdylib at `src/main/resources/native/{os}-{arch}/` to bundle it inside the JAR for single-file deployment.\n\n---\n\n## Zero-Config Defaults\n\nOut of the box the autoconfigure module wires up:\n\n| Concern | Default | Override |\n|---------|---------|----------|\n| App selection | Read `X-Vespera-App` request header; absent → default app | Property `vespera.bridge.app-header`, or custom `AppNameResolver` bean |\n| Dispatch mode | `SmartDispatchModeResolver` since 0.2.0 — `DIRECT` for small/bodyless idempotent, `SYNC` for small non-idempotent, `BIDIRECTIONAL_STREAMING` for the rest | Property `vespera.bridge.dispatch-mode: bidirectional-streaming`, or custom `DispatchModeResolver` bean |\n| URL pattern | `@RequestMapping(\"/**\")` catch-all | Set `vespera.bridge.controller-enabled: false` and supply your own controller |\n\n---\n\n## Customization\n\n### Tweak via application.yml\n\n```yaml\nvespera:\n bridge:\n app-header: X-My-App # change the header that selects the app\n controller-enabled: true # set false to disable the proxy controller\n```\n\n### Custom App-Selection Strategy\n\n```java\n@Bean\npublic AppNameResolver myAppResolver() {\n return request -> {\n String uri = request.getRequestURI();\n if (uri.startsWith(\"/admin/\")) return \"admin\";\n if (uri.startsWith(\"/public/\")) return \"public\";\n return null; // default app\n };\n}\n```\n\nSpring's `@ConditionalOnMissingBean` automatically disables `HeaderAppNameResolver` when you supply your own bean.\n\n### Custom Dispatch-Mode Policy\n\n```java\n@Bean\npublic DispatchModeResolver myModeResolver() {\n return request -> {\n long contentLength = request.getContentLengthLong();\n if (contentLength >= 0 && contentLength < 4096\n && \"application/json\".equals(request.getContentType())) {\n return DispatchMode.SYNC;\n }\n return DispatchMode.BIDIRECTIONAL_STREAMING;\n };\n}\n```\n\n### BYO Controller\n\n```yaml\nvespera:\n bridge:\n controller-enabled: false\n```\n\n```java\n@RestController\npublic class MyController {\n @PostMapping(\"/api/admin/{path}\")\n public ResponseEntity adminRoute(@PathVariable String path, @RequestBody byte[] body) {\n byte[] wire = VesperaBridge.encodeRequest(\n \"admin\", \"POST\", \"/\" + path, null,\n Map.of(\"content-type\", \"application/json\"), body);\n byte[] resp = VesperaBridge.dispatchBytes(wire);\n DecodedResponse d = VesperaBridge.decodeResponse(resp);\n return ResponseEntity.status(d.status()).body(d.bodyBytes());\n }\n}\n```\n","title":"jni_app! & VesperaBridge","url":"/documentation/theme/theme-1"},{"text":"# Dispatch Modes & Wire Format\n\n## Binary Wire Format\n\nBoth request and response use the same length-prefixed layout:\n\n```\nbytes 0..4 : u32 BE = header_json byte length N\nbytes 4..4+N : UTF-8 JSON\n (request) { \"v\":1, \"method\", \"path\",\n \"query\"?, \"headers\"?

    \n\n### Choosing a Mode\n\n- Small JSON RPC, single request/response → `dispatchBytes`\n- Hot small/bounded payloads where JNI copy overhead matters → `dispatchDirect` / `dispatchDirectPooled`\n- Async I/O coordination (parallel Java requests, non-blocking) → `dispatchAsync` + `CompletableFuture`\n- Large download / streaming response (video, PDF, SSE) → `dispatchStreaming` + `OutputStream`\n- Large upload + large download (file transfer, video transcoding) → `dispatchFullStreaming` + `InputStream` + `OutputStream`\n- The `*WithHeader` variants let Spring-style controllers commit status/headers before the first body byte is written\n\n## SmartDispatchModeResolver (Default since 0.2.0)\n\nThe autoconfigured default since vespera-bridge 0.2.0 picks the cheapest safe path per request. Measured on a `GET /health` round-trip through the real JNI boundary:\n\n| Request shape | Mode | ns / round-trip |\n|---------------|------|-----------------|\n| Small/bodyless + idempotent (GET/HEAD/PUT/DELETE/OPTIONS, ≤ 256 KiB) | `DIRECT` | ~2,200 |\n| Small (≤ 256 KiB Content-Length) + non-idempotent (POST/PATCH) | `SYNC` | ~3,200 |\n| Large or unknown-length body | `BIDIRECTIONAL_STREAMING` | ~24,100 |\n\nTrade-offs:\n- **DIRECT** writes the wire response straight into a pooled per-thread direct `ByteBuffer` (64 KiB → `vespera.direct.maxBufferBytes`, default 4 MiB). Responses larger than the pooled buffer trigger a single retry that **re-runs the Rust handler** — which is why DIRECT is gated on idempotent methods only.\n- **SYNC** fully buffers the response on the JVM heap. The 256 KiB request-size gate keeps the response size reasonable for JSON-RPC-shaped traffic.\n- **BIDIRECTIONAL_STREAMING** is unchanged for large/unknown-length bodies — multi-GB upload + multi-GB download runs chunk-bounded, ~32 KiB resident each side.\n\nRestore the pre-0.2.0 default (every request that may carry a body streams both ways, ~24 µs uniform):\n\n```yaml\nvespera:\n bridge:\n dispatch-mode: bidirectional-streaming\n```\n\n## Direct Buffer Dispatch\n\n`dispatchDirect(ByteBuffer in, int inLen, ByteBuffer out)` eliminates the two JNI `GetByteArrayRegion`/`SetByteArrayRegion` copies that `dispatchBytes` pays. The response is streamed straight into the out buffer — no intermediate `Vec`. Measured at **1.4–3.4× per round-trip** versus `dispatchBytes` depending on payload size.\n\nContract:\n- Both buffers MUST be direct (`ByteBuffer.allocateDirect`); heap buffers are rejected with `IllegalArgumentException`\n- The request is read from absolute offsets `in[0..inLen]` — the buffer's position/limit are ignored; `inLen` is authoritative\n- Return `>= 0`: a complete wire response occupies `out[0..n]`\n- Return `< 0`: `-(requiredSize)` — the response did not fit; **retrying re-runs the Rust handler**, so only retry idempotent requests\n- `Integer.MIN_VALUE`: response exceeds 2 GiB\n\n`dispatchDirectPooled(byte[] wireRequest, boolean retryOnOverflow)` wraps the raw call with per-thread reusable direct buffers (64 KiB initial, doubling up to `vespera.direct.maxBufferBytes`, default 4 MiB).\n\n## Direct API (Without the Proxy Controller)\n\n```java\nimport com.devfive.vespera.bridge.VesperaBridge;\nimport com.devfive.vespera.bridge.VesperaBridge.DecodedResponse;\n\n// 1.

The owned `byte[]` materialisation moved to `DecodedResponse.bodyBytes()`. Callers that previously used `body()` as `byte[]` must switch to `bodyBytes()`.\n\n## Async Dispatch\n\n```java\nCompletableFuture future = VesperaBridge.dispatch(wireRequest);\n\nfuture.thenAccept(wireResponse -> {\n DecodedResponse resp = VesperaBridge.decodeResponse(wireResponse);\n System.out.println(\"Status: \" + resp.status());\n});\n```\n\nThe future is **always** completed with a valid wire response, even on Rust panics or JNI conversion failures. You will never see a dangling future.\n\n## Streaming Dispatch\n\n```java\nbyte[] wireRequest = VesperaBridge.encodeRequest(\n \"GET\", \"/files/large.pdf\", null, Map.of(), new byte[0]);\n\ntry (ByteArrayOutputStream sink = new ByteArrayOutputStream()) {\n byte[] headerOnly = VesperaBridge.dispatchStreaming(wireRequest, sink);\n DecodedResponse meta = VesperaBridge.decodeResponse(headerOnly);\n System.out.println(\"Status: \" + meta.status());\n System.out.println(\"Body size: \" + sink.size());\n}\n```\n\n## Bidirectional Streaming\n\n```java\ntry (InputStream upload = Files.newInputStream(Path.of(\"huge.mp4\"));\n OutputStream download = Files.newOutputStream(Path.of(\"transcoded.mp4\"))) {\n\n byte[] wireHeader = VesperaBridge.encodeRequestHeader(\n \"POST\", \"/transcode\", null,\n Map.of(\"content-type\", \"video/mp4\"));\n\n byte[] respHeader = VesperaBridge.dispatchFullStreaming(\n wireHeader, upload, download);\n\n DecodedResponse meta = VesperaBridge.decodeResponse(respHeader);\n System.out.println(\"Status: \" + meta.status());\n}\n```\n\nA 1 GiB upload paired with a 1 GiB download runs in low-single-digit MiB resident memory on each side. Backpressure is enforced naturally — if Axum reads slowly, `InputStream.read()` blocks on the bounded channel.\n","title":"Dispatch Modes & Wire Format","url":"/documentation/theme/theme-2"},{"text":"# Streaming & Multi-App\n\n## Streaming Tuning\n\nBoth streaming knobs are fixed for the process lifetime once the first dispatch runs. Configuration precedence (first hit wins):\n\n1. **Programmatic setter** — `VesperaBridge.configureStreaming(chunkBytes, channelCapacity)` (call before or after `init`)\n2. **System properties** — `vespera.streaming.chunkBytes`, `vespera.streaming.channelCapacity`\n3. **Environment variables** — `VESPERA_STREAMING_CHUNK_BYTES`, `VESPERA_STREAMING_CHANNEL_CAPACITY`\n4. **Built-in defaults** — 64 KiB chunk size, 16 channel slots\n\n| Setting | System property | Env var | Default | Range |\n|---------|----------------|---------|---------|-------|\n| Chunk buffer size | `vespera.streaming.chunkBytes` | `VESPERA_STREAMING_CHUNK_BYTES` | 64 KiB | 4 KiB – 8 MiB |\n| Request channel slots | `vespera.streaming.channelCapacity` | `VESPERA_STREAMING_CHANNEL_CAPACITY` | 16 | 1 – 1024 |\n| Tokio worker threads | `vespera.runtime.workerThreads` | `VESPERA_RUNTIME_WORKERS` | logical CPUs | 1 – 1024 |\n\n### Java API\n\nCall before `VesperaBridge.init(...)` for guaranteed precedence:\n\n```java\nVesperaBridge.configureStreaming(\n 131072, // chunkBytes: 128 KiB (clamped to 4 KiB – 8 MiB)\n 32 // channelCapacity: 32 slots (clamped to 1 – 1024)\n);\nVesperaBridge.init(\"my_rust_lib\");\n```\n\nWhen called before `init()`, values are stored as pending and applied immediately after the native library loads — before any dispatch can occur. This ensures the programmatic setter beats system properties and environment variables.\n\nThrows `IllegalArgumentException` if `chunkBytes` is outside `[4096, 8388608]` or `channelCapacity` is outside `[1, 1024]`.\n\n### System Properties\n\n```bash\njava -Dvespera.streaming.chunkBytes=131072 \\\n -Dvespera.streaming.channelCapacity=32 \\\n -jar app.jar\n```\n\n### Environment Variables\n\n```bash\nexport VESPERA_STREAMING_CHUNK_BYTES=131072\nexport VESPERA_STREAMING_CHANNEL_CAPACITY=32\njava -jar app.jar\n```\n\n### Tuning Tips\n\n- Larger chunks reduce the per-chunk JNI crossing cost (one `SetByteArrayRegion` + one `OutputStream.write` per chunk) at the price of per-stream memory. 256 KiB is a reasonable ceiling for throughput-oriented deployments.\n- The Tokio worker-thread knob caps Rust's shared runtime — useful when the JVM's own pools (Tomcat request threads, virtual-thread carriers) compete with Tokio for the same cores, or when a container CPU limit is lower than the host's logical CPU count.\n\n---\n\n## Multi-App Routing\n\nMulti-app routing is primarily a feature for external-dispatcher scenarios — JNI (Java host picks app per request via header), WebAssembly bridge, C FFI, or any in-process embedding where the host distinguishes between multiple independent Vespera API surfaces.\n\n### Rust Side\n\n```rust\npub fn create_app() -> axum::Router { vespera!(title = \"Default\") }\npub fn admin_app() -> axum::Router { vespera!(dir = \"admin_routes\", title = \"Admin\") }\npub fn public_app() -> axum::Router { vespera!(dir = \"public_routes\", title = \"Public\") }\n\nvespera::jni_apps! {\n \"_default\" => create_app,\n \"admin\" => admin_app,\n \"public\" => public_app,\n}\n```\n\n`jni_apps!` is the primary multi-app API. `jni_app!(create_app)` is syntactic sugar for a single default app.\n\n### Java Side\n\nThe default `HeaderAppNameResolver` selects an app per request via the `X-Vespera-App` header:\n\n```bash\n# Default app (no header)\ncurl http://localhost:8080/health\n\n# Admin app\ncurl -H \"X-Vespera-App: admin\" http://localhost:8080/dashboard\n\n# Public app\ncurl -H \"X-Vespera-App: public\" http://localhost:8080/info\n```\n\nEach app's URLs are independent — the same `/users` path can mean different things in `admin` vs `public` apps. Unknown app names return `404`; invalid app names (special characters, > 64 bytes) return `400`.\n\n### Custom App-Selection Strategy\n\n```java\n@Bean\npublic AppNameResolver myAppResolver() {\n // App name from the first path segment:\n // /admin/dashboard → app \"admin\", path \"/dashboard\"\n // /public/info → app \"public\", path \"/info\"\n return request -> {\n String uri = request.getRequestURI();\n if (uri.startsWith(\"/admin/\")) return \"admin\";\n if (uri.startsWith(\"/public/\")) return \"public\";\n return null; // default app\n };\n}\n```\n\n---\n\n## Virtual Thread (Project Loom) Limitation\n\nThe pooled direct-buffer methods (`dispatchDirectPooled`) use `ThreadLocal` to maintain per-thread reusable buffers. In Java 21+, `ThreadLocal` binds to the **virtual thread** (not the carrier thread) — so in a virtual-thread-per-request server, each virtual thread allocates a fresh direct buffer and loses all pooling benefit. Direct memory accumulates until the virtual thread is garbage-collected, potentially causing memory pressure under high concurrency.\n\n**Recommendations for virtual-thread deployments:**\n\n- Set `vespera.bridge.dispatch-mode=bidirectional-streaming` to opt out of the smart default, so `DIRECT` is never chosen by the autoconfigured resolver.\n- Or use `dispatchBytes`, `dispatchStreaming`, or `dispatchFullStreaming` directly instead of the pooled direct variants.\n- Or run dispatch on a bounded platform-thread executor (e.g. a `ForkJoinPool` with a fixed parallelism cap).\n- Or lower `vespera.direct.maxBufferBytes` to reduce per-thread allocation size.\n\n`DispatchMode.BIDIRECTIONAL_STREAMING` is safe for virtual threads and handles all payload sizes without pooling.\n\n---\n\n## 0.2.0 Breaking Changes\n\n### 1. Default DispatchModeResolver Flipped to SmartDispatchModeResolver\n\nPre-0.2.0 the autoconfigured default was `BidirectionalStreamingDispatchModeResolver` — every request that may carry a body streamed both ways, ~24.1 µs per round-trip uniform. Since 0.2.0 the default is `SmartDispatchModeResolver`.\n\n| Request shape | Pre-0.2.0 mode | 0.2.0+ mode |\n|---------------|----------------|-------------|\n| Small/bodyless idempotent (GET/HEAD/PUT/DELETE/OPTIONS, ≤ 256 KiB CL or no CL) | `STREAMING` / `BIDIRECTIONAL_STREAMING` | `DIRECT` |\n| Small non-idempotent (POST/PATCH, ≤ 256 KiB CL) | `BIDIRECTIONAL_STREAMING` | `SYNC` |\n| Large or unknown-length body | `BIDIRECTIONAL_STREAMING` | `BIDIRECTIONAL_STREAMING` |\n\nOpt out (restore the pre-0.2.0 default):\n\n```yaml\nvespera:\n bridge:\n dispatch-mode: bidirectional-streaming\n```\n\nOr register a custom `DispatchModeResolver` bean — `@ConditionalOnMissingBean` ensures it wins over both the property and the autoconfigured default.\n\n### 2. DecodedResponse.body() Returns ByteBuffer\n\n`DecodedResponse.body()` now returns a read-only `java.nio.ByteBuffer` (zero-copy view over the wire bytes). The owned `byte[]` materialisation moved to `DecodedResponse.bodyBytes()`.\n\n```java\n// Before 0.2.0\nbyte[] body = resp.body();\n\n// After 0.2.0\nbyte[] body = resp.bodyBytes(); // owned copy\nByteBuffer view = resp.body(); // zero-copy view\n```\n\nCallers that previously consumed `body()` as `byte[]` must switch to `bodyBytes()`.\n\n---\n\n## Migrating from the JSON-Envelope Bridge (≤ 0.0.13)\n\nThe pre-0.0.14 bridge used `dispatch(String) → String` with base64-encoded binary bodies.\n\n| Before | After |\n|--------|-------|\n| `VesperaBridge.dispatch(json)` | `encodeRequest(...)` → `dispatchBytes(...)` → `decodeResponse(...)` |\n| `body_bytes_b64` field on the response JSON | raw body bytes after the wire header (no base64) |\n| ~33% size overhead on binary bodies | zero overhead |\n\nExisting users of `VesperaProxyController` need no code change — the controller was rewritten to the new wire path internally. Direct callers of `VesperaBridge.dispatch(String)` must update; the old method was removed in 0.0.14.\n","title":"Streaming & Multi-App","url":"/documentation/theme/theme-3"}] \ No newline at end of file diff --git a/apps/landing/src/app/documentation/[...name]/overview.mdx b/apps/landing/src/app/documentation/[...name]/overview.mdx index 96636751..0dba9e87 100644 --- a/apps/landing/src/app/documentation/[...name]/overview.mdx +++ b/apps/landing/src/app/documentation/[...name]/overview.mdx @@ -106,7 +106,7 @@ Vespera scans your `src/routes/` folder at compile time, extracts every `#[vespe ## JNI Performance Numbers -When embedding Vespera inside a Java/Spring application via JNI, the `SmartDispatchModeResolver` (default since vespera-bridge 1.0.0) picks the cheapest safe path per request.

Measured on a `GET /health` round-trip through the real JNI boundary (AMD Ryzen 9 9950X, Java 21, Windows 11):\n\n\n \n \n Request shape\n Mode\n ns / round-trip\n \n \n \n \n Small/bodyless + idempotent (GET/HEAD/PUT/DELETE/OPTIONS, ≤ 256 KiB)\n `DIRECT` (pooled direct buffers)\n ~2,200 ns\n \n \n Small (≤ 256 KiB) + non-idempotent (POST/PATCH)\n `SYNC` (heap-buffered)\n ~3,200 ns\n \n \n Large or unknown-length body\n `BIDIRECTIONAL_STREAMING`\n ~24,100 ns\n \n \n

      \n\nThe `direct_pooled` path completes a tiny `/health` round-trip in **2,349 ns/op** — **1.55× faster** than the pre-0.2.0 sync baseline (3,643 ns/op).\n\n## How It Works\n\n```\nsrc/routes/\n├── mod.rs → /\n├── users.rs → /users\n└── admin/\n └── stats.rs → /admin/stats\n```\n\n1.

In-process JNI dispatch eliminates that entirely:\n\n- No TCP connection overhead\n- No JSON serialization of the envelope\n- Binary bodies (multipart, PDFs, images) travel as raw bytes — no base64\n- Measured latency for small requests: **~2,200 ns** with the `DIRECT` dispatch mode\n\n## Quick Navigation\n\n- [jni_app! & VesperaBridge](/documentation/theme/theme-1) — Rust setup, Java setup, native library loading\n- [Dispatch Modes & Wire Format](/documentation/theme/theme-2) — all seven dispatch methods, binary wire layout, `SmartDispatchModeResolver` defaults\n- [Streaming & Multi-App](/documentation/theme/theme-3) — streaming tuning, multi-app routing, virtual thread notes, 0.2.0 breaking changes\n\n## Two-Line Integration\n\n**Rust side:**\n\n```rust\npub fn create_app() -> vespera::axum::Router {\n vespera!(title = \"My API\")\n}\n\nvespera::jni_app!(create_app);\n```\n\n**Java side:**\n\n```java\n@SpringBootApplication\n@ComponentScan(basePackages = {\"com.example.app\", \"com.devfive.vespera.bridge\"})\npublic class MyApp {\n public static void main(String[] args) {\n VesperaBridge.init(\"my_rust_lib\");\n SpringApplication.run(MyApp.class, args);\n }\n}\n```\n\nThat's it. `VesperaProxyController` is autoconfigured and forwards every HTTP request to Rust. Zero controller code, zero `application.yml` config, zero extra imports beyond the Spring Boot starter.\n","title":"JNI / Java Integration","url":"/documentation/theme"},{"text":"# jni_app! & VesperaBridge\n\n## Rust Setup\n\n### 1. Enable the JNI Feature\n\n```toml\n[dependencies]\nvespera = { version = \"0.1\", features = [\"jni\"] }\n```\n\nThe `jni` feature implies `inprocess` — both are enabled automatically.\n\n### 2. Export Your App\n\nIn your cdylib crate's `src/lib.rs`:\n\n```rust\nuse vespera::{axum, vespera};\n\npub fn create_app() -> axum::Router {\n vespera!(title = \"My API\", version = \"1.0.0\")\n}\n\n// Single app — generates JNI_OnLoad and the dispatch symbol\nvespera::jni_app!(create_app);\n```\n\n`jni_app!` generates all JNI boilerplate: `JNI_OnLoad`, the Tokio runtime, and the seven dispatch symbols. You write zero JNI code.\n\n### 3. Build as a cdylib\n\n```toml\n[lib]\ncrate-type = [\"cdylib\"]\n```\n\n```bash\ncargo build --release\n# Produces: target/release/libmy_rust_lib.so (Linux)\n# target/release/my_rust_lib.dll (Windows)\n# target/release/libmy_rust_lib.dylib (macOS)\n```\n\n---\n\n## Java Setup\n\n### Maven\n\n```xml\n\n kr.devfive\n vespera-bridge\n 0.2.0\n\n```\n\n### Gradle (Kotlin DSL)\n\n```kotlin\ndependencies {\n implementation(\"kr.devfive:vespera-bridge:0.2.0\")\n}\n```\n\n### Gradle Plugin (Recommended)\n\nThe `kr.devfive.vespera-bridge` Gradle plugin replaces ~22 lines of native-library-bundling boilerplate with a 5-line block:\n\n```kotlin\nplugins {\n id(\"kr.devfive.vespera-bridge\") version \"0.1.1\"\n}\n\nvespera {\n crateName.set(\"my_rust_lib\")\n cargoRoot.set(rootProject.layout.projectDirectory.dir(\"../..\"))\n bridgeVersion.set(\"0.2.0\")\n}\n```\n\nThe plugin auto-wires `bundleNativeLib` (cdylib → `resources/native/-/`), the `processResources` dependency, and the `vespera-bridge` implementation dependency.\n\n### Spring Boot Application\n\n```java\n@SpringBootApplication\n@ComponentScan(basePackages = {\"com.example.app\", \"com.devfive.vespera.bridge\"})\npublic class MyApp {\n public static void main(String[] args) {\n VesperaBridge.init(\"my_rust_lib\"); // loads cdylib (bundled or system path)\n SpringApplication.run(MyApp.class, args);\n }\n}\n```\n\n`VesperaProxyController` is autoconfigured via Spring Boot's `AutoConfiguration.imports`. It registers a `@RequestMapping(\"/**\")` catch-all that forwards every HTTP request to Rust. The routes published in Vespera's generated `openapi.json` are reachable at the same URLs through Spring.\n\n---\n\n## Native Library Loading\n\n`VesperaBridge.init(\"crateName\")` tries two paths in order:\n\n1. **Bundled** — looks up `native/{os}-{arch}/{libname}` inside the running JAR's classpath. If found, the file is extracted to a temp file (auto-deleted on JVM exit) and loaded via `System.load`.\n2. **Fallback** — `System.loadLibrary(\"crateName\")` searches `java.library.path`.\n\nSupported platform triples: `linux-x86_64`, `linux-aarch64`, `macos-x86_64`, `macos-aarch64`, `windows-x86_64`.\n\nPlace the cdylib at `src/main/resources/native/{os}-{arch}/` to bundle it inside the JAR for single-file deployment.\n\n---\n\n## Zero-Config Defaults\n\nOut of the box the autoconfigure module wires up:\n\n| Concern | Default | Override |\n|---------|---------|----------|\n| App selection | Read `X-Vespera-App` request header; absent → default app | Property `vespera.bridge.app-header`, or custom `AppNameResolver` bean |\n| Dispatch mode | `SmartDispatchModeResolver` since 0.2.0 — `DIRECT` for small/bodyless idempotent, `SYNC` for small non-idempotent, `BIDIRECTIONAL_STREAMING` for the rest | Property `vespera.bridge.dispatch-mode: bidirectional-streaming`, or custom `DispatchModeResolver` bean |\n| URL pattern | `@RequestMapping(\"/**\")` catch-all | Set `vespera.bridge.controller-enabled: false` and supply your own controller |\n\n---\n\n## Customization\n\n### Tweak via application.yml\n\n```yaml\nvespera:\n bridge:\n app-header: X-My-App # change the header that selects the app\n controller-enabled: true # set false to disable the proxy controller\n```\n\n### Custom App-Selection Strategy\n\n```java\n@Bean\npublic AppNameResolver myAppResolver() {\n return request -> {\n String uri = request.getRequestURI();\n if (uri.startsWith(\"/admin/\")) return \"admin\";\n if (uri.startsWith(\"/public/\")) return \"public\";\n return null; // default app\n };\n}\n```\n\nSpring's `@ConditionalOnMissingBean` automatically disables `HeaderAppNameResolver` when you supply your own bean.\n\n### Custom Dispatch-Mode Policy\n\n```java\n@Bean\npublic DispatchModeResolver myModeResolver() {\n return request -> {\n long contentLength = request.getContentLengthLong();\n if (contentLength >= 0 && contentLength < 4096\n && \"application/json\".equals(request.getContentType())) {\n return DispatchMode.SYNC;\n }\n return DispatchMode.BIDIRECTIONAL_STREAMING;\n };\n}\n```\n\n### BYO Controller\n\n```yaml\nvespera:\n bridge:\n controller-enabled: false\n```\n\n```java\n@RestController\npublic class MyController {\n @PostMapping(\"/api/admin/{path}\")\n public ResponseEntity adminRoute(@PathVariable String path, @RequestBody byte[] body) {\n byte[] wire = VesperaBridge.encodeRequest(\n \"admin\", \"POST\", \"/\" + path, null,\n Map.of(\"content-type\", \"application/json\"), body);\n byte[] resp = VesperaBridge.dispatchBytes(wire);\n DecodedResponse d = VesperaBridge.decodeResponse(resp);\n return ResponseEntity.status(d.status()).body(d.bodyBytes());\n }\n}\n```\n","title":"jni_app! & VesperaBridge","url":"/documentation/theme/theme-1"},{"text":"# Dispatch Modes & Wire Format\n\n## Binary Wire Format\n\nBoth request and response use the same length-prefixed layout:\n\n```\nbytes 0..4 : u32 BE = header_json byte length N\nbytes 4..4+N : UTF-8 JSON\n (request) { \"v\":1, \"method\", \"path\",\n \"query\"?, \"headers\"?

      \n\n### Choosing a Mode\n\n- Small JSON RPC, single request/response → `dispatchBytes`\n- Hot small/bounded payloads where JNI copy overhead matters → `dispatchDirect` / `dispatchDirectPooled`\n- Async I/O coordination (parallel Java requests, non-blocking) → `dispatchAsync` + `CompletableFuture`\n- Large download / streaming response (video, PDF, SSE) → `dispatchStreaming` + `OutputStream`\n- Large upload + large download (file transfer, video transcoding) → `dispatchFullStreaming` + `InputStream` + `OutputStream`\n- The `*WithHeader` variants let Spring-style controllers commit status/headers before the first body byte is written\n\n## SmartDispatchModeResolver (Default since 0.2.0)\n\nThe autoconfigured default since vespera-bridge 0.2.0 picks the cheapest safe path per request. Measured on a `GET /health` round-trip through the real JNI boundary:\n\n| Request shape | Mode | ns / round-trip |\n|---------------|------|-----------------|\n| Small/bodyless + idempotent (GET/HEAD/PUT/DELETE/OPTIONS, ≤ 256 KiB) | `DIRECT` | ~2,200 |\n| Small (≤ 256 KiB Content-Length) + non-idempotent (POST/PATCH) | `SYNC` | ~3,200 |\n| Large or unknown-length body | `BIDIRECTIONAL_STREAMING` | ~24,100 |\n\nTrade-offs:\n- **DIRECT** writes the wire response straight into a pooled per-thread direct `ByteBuffer` (64 KiB → `vespera.direct.maxBufferBytes`, default 4 MiB). Responses larger than the pooled buffer trigger a single retry that **re-runs the Rust handler** — which is why DIRECT is gated on idempotent methods only.\n- **SYNC** fully buffers the response on the JVM heap. The 256 KiB request-size gate keeps the response size reasonable for JSON-RPC-shaped traffic.\n- **BIDIRECTIONAL_STREAMING** is unchanged for large/unknown-length bodies — multi-GB upload + multi-GB download runs chunk-bounded, ~32 KiB resident each side.\n\nRestore the pre-0.2.0 default (every request that may carry a body streams both ways, ~24 µs uniform):\n\n```yaml\nvespera:\n bridge:\n dispatch-mode: bidirectional-streaming\n```\n\n## Direct Buffer Dispatch\n\n`dispatchDirect(ByteBuffer in, int inLen, ByteBuffer out)` eliminates the two JNI `GetByteArrayRegion`/`SetByteArrayRegion` copies that `dispatchBytes` pays. The response is streamed straight into the out buffer — no intermediate `Vec`. Measured at **1.4–3.4× per round-trip** versus `dispatchBytes` depending on payload size.\n\nContract:\n- Both buffers MUST be direct (`ByteBuffer.allocateDirect`); heap buffers are rejected with `IllegalArgumentException`\n- The request is read from absolute offsets `in[0..inLen]` — the buffer's position/limit are ignored; `inLen` is authoritative\n- Return `>= 0`: a complete wire response occupies `out[0..n]`\n- Return `< 0`: `-(requiredSize)` — the response did not fit; **retrying re-runs the Rust handler**, so only retry idempotent requests\n- `Integer.MIN_VALUE`: response exceeds 2 GiB\n\n`dispatchDirectPooled(byte[] wireRequest, boolean retryOnOverflow)` wraps the raw call with per-thread reusable direct buffers (64 KiB initial, doubling up to `vespera.direct.maxBufferBytes`, default 4 MiB).\n\n## Direct API (Without the Proxy Controller)\n\n```java\nimport com.devfive.vespera.bridge.VesperaBridge;\nimport com.devfive.vespera.bridge.VesperaBridge.DecodedResponse;\n\n// 1. Initialise once at startup\nVesperaBridge.init(\"my_rust_lib\");\n\n// 2.

Dispatch through Rust\nbyte[] wireResponse = VesperaBridge.dispatchBytes(wireRequest);\n\n// 4. Decode\nDecodedResponse resp = VesperaBridge.decodeResponse(wireResponse);\nSystem.out.println(resp.status()); // 200\nSystem.out.println(resp.headers()); // { \"content-type\": \"application/json\", … }\nSystem.out.println(new String(resp.bodyBytes())); // copies the raw response body\n```\n\n> **0.2.0 breaking change:** `DecodedResponse.body()` now returns a read-only `java.nio.ByteBuffer` (zero-copy view over the wire bytes). The owned `byte[]` materialisation moved to `DecodedResponse.bodyBytes()`. Callers that previously used `body()` as `byte[]` must switch to `bodyBytes()`.\n\n## Async Dispatch\n\n```java\nCompletableFuture future = VesperaBridge.dispatch(wireRequest);\n\nfuture.thenAccept(wireResponse -> {\n DecodedResponse resp = VesperaBridge.decodeResponse(wireResponse);\n System.out.println(\"Status: \" + resp.status());\n});\n```\n\nThe future is **always** completed with a valid wire response, even on Rust panics or JNI conversion failures. You will never see a dangling future.\n\n## Streaming Dispatch\n\n```java\nbyte[] wireRequest = VesperaBridge.encodeRequest(\n \"GET\", \"/files/large.pdf\", null, Map.of(), new byte[0]);\n\ntry (ByteArrayOutputStream sink = new ByteArrayOutputStream()) {\n byte[] headerOnly = VesperaBridge.dispatchStreaming(wireRequest, sink);\n DecodedResponse meta = VesperaBridge.decodeResponse(headerOnly);\n System.out.println(\"Status: \" + meta.status());\n System.out.println(\"Body size: \" + sink.size());\n}\n```\n\n## Bidirectional Streaming\n\n```java\ntry (InputStream upload = Files.newInputStream(Path.of(\"huge.mp4\"));\n OutputStream download = Files.newOutputStream(Path.of(\"transcoded.mp4\"))) {\n\n byte[] wireHeader = VesperaBridge.encodeRequestHeader(\n \"POST\", \"/transcode\", null,\n Map.of(\"content-type\", \"video/mp4\"));\n\n byte[] respHeader = VesperaBridge.dispatchFullStreaming(\n wireHeader, upload, download);\n\n DecodedResponse meta = VesperaBridge.decodeResponse(respHeader);\n System.out.println(\"Status: \" + meta.status());\n}\n```\n\nA 1 GiB upload paired with a 1 GiB download runs in low-single-digit MiB resident memory on each side. Backpressure is enforced naturally — if Axum reads slowly, `InputStream.read()` blocks on the bounded channel.\n","title":"Dispatch Modes & Wire Format","url":"/documentation/theme/theme-2"},{"text":"# Streaming & Multi-App\n\n## Streaming Tuning\n\nBoth streaming knobs are fixed for the process lifetime once the first dispatch runs. Configuration precedence (first hit wins):\n\n1. **Programmatic setter** — `VesperaBridge.configureStreaming(chunkBytes, channelCapacity)` (call before or after `init`)\n2. **System properties** — `vespera.streaming.chunkBytes`, `vespera.streaming.channelCapacity`\n3. **Environment variables** — `VESPERA_STREAMING_CHUNK_BYTES`, `VESPERA_STREAMING_CHANNEL_CAPACITY`\n4. **Built-in defaults** — 64 KiB chunk size, 16 channel slots\n\n| Setting | System property | Env var | Default | Range |\n|---------|----------------|---------|---------|-------|\n| Chunk buffer size | `vespera.streaming.chunkBytes` | `VESPERA_STREAMING_CHUNK_BYTES` | 64 KiB | 4 KiB – 8 MiB |\n| Request channel slots | `vespera.streaming.channelCapacity` | `VESPERA_STREAMING_CHANNEL_CAPACITY` | 16 | 1 – 1024 |\n| Tokio worker threads | `vespera.runtime.workerThreads` | `VESPERA_RUNTIME_WORKERS` | logical CPUs | 1 – 1024 |\n\n### Java API\n\nCall before `VesperaBridge.init(...)` for guaranteed precedence:\n\n```java\nVesperaBridge.configureStreaming(\n 131072, // chunkBytes: 128 KiB (clamped to 4 KiB – 8 MiB)\n 32 // channelCapacity: 32 slots (clamped to 1 – 1024)\n);\nVesperaBridge.init(\"my_rust_lib\");\n```\n\nWhen called before `init()`, values are stored as pending and applied immediately after the native library loads — before any dispatch can occur. This ensures the programmatic setter beats system properties and environment variables.\n\nThrows `IllegalArgumentException` if `chunkBytes` is outside `[4096, 8388608]` or `channelCapacity` is outside `[1, 1024]`.\n\n### System Properties\n\n```bash\njava -Dvespera.streaming.chunkBytes=131072 \\\n -Dvespera.streaming.channelCapacity=32 \\\n -jar app.jar\n```\n\n### Environment Variables\n\n```bash\nexport VESPERA_STREAMING_CHUNK_BYTES=131072\nexport VESPERA_STREAMING_CHANNEL_CAPACITY=32\njava -jar app.jar\n```\n\n### Tuning Tips\n\n- Larger chunks reduce the per-chunk JNI crossing cost (one `SetByteArrayRegion` + one `OutputStream.write` per chunk) at the price of per-stream memory. 256 KiB is a reasonable ceiling for throughput-oriented deployments.\n- The Tokio worker-thread knob caps Rust's shared runtime — useful when the JVM's own pools (Tomcat request threads, virtual-thread carriers) compete with Tokio for the same cores, or when a container CPU limit is lower than the host's logical CPU count.\n\n---\n\n## Multi-App Routing\n\nMulti-app routing is primarily a feature for external-dispatcher scenarios — JNI (Java host picks app per request via header), WebAssembly bridge, C FFI, or any in-process embedding where the host distinguishes between multiple independent Vespera API surfaces.\n\n### Rust Side\n\n```rust\npub fn create_app() -> axum::Router { vespera!(title = \"Default\") }\npub fn admin_app() -> axum::Router { vespera!(dir = \"admin_routes\", title = \"Admin\") }\npub fn public_app() -> axum::Router { vespera!(dir = \"public_routes\", title = \"Public\") }\n\nvespera::jni_apps! {\n \"_default\" => create_app,\n \"admin\" => admin_app,\n \"public\" => public_app,\n}\n```\n\n`jni_apps!` is the primary multi-app API. `jni_app!(create_app)` is syntactic sugar for a single default app.\n\n### Java Side\n\nThe default `HeaderAppNameResolver` selects an app per request via the `X-Vespera-App` header:\n\n```bash\n# Default app (no header)\ncurl http://localhost:8080/health\n\n# Admin app\ncurl -H \"X-Vespera-App: admin\" http://localhost:8080/dashboard\n\n# Public app\ncurl -H \"X-Vespera-App: public\" http://localhost:8080/info\n```\n\nEach app's URLs are independent — the same `/users` path can mean different things in `admin` vs `public` apps. Unknown app names return `404`; invalid app names (special characters, > 64 bytes) return `400`.\n\n### Custom App-Selection Strategy\n\n```java\n@Bean\npublic AppNameResolver myAppResolver() {\n // App name from the first path segment:\n // /admin/dashboard → app \"admin\", path \"/dashboard\"\n // /public/info → app \"public\", path \"/info\"\n return request -> {\n String uri = request.getRequestURI();\n if (uri.startsWith(\"/admin/\")) return \"admin\";\n if (uri.startsWith(\"/public/\")) return \"public\";\n return null; // default app\n };\n}\n```\n\n---\n\n## Virtual Thread (Project Loom) Limitation\n\nThe pooled direct-buffer methods (`dispatchDirectPooled`) use `ThreadLocal` to maintain per-thread reusable buffers. In Java 21+, `ThreadLocal` binds to the **virtual thread** (not the carrier thread) — so in a virtual-thread-per-request server, each virtual thread allocates a fresh direct buffer and loses all pooling benefit. Direct memory accumulates until the virtual thread is garbage-collected, potentially causing memory pressure under high concurrency.\n\n**Recommendations for virtual-thread deployments:**\n\n- Set `vespera.bridge.dispatch-mode=bidirectional-streaming` to opt out of the smart default, so `DIRECT` is never chosen by the autoconfigured resolver.\n- Or use `dispatchBytes`, `dispatchStreaming`, or `dispatchFullStreaming` directly instead of the pooled direct variants.\n- Or run dispatch on a bounded platform-thread executor (e.g. a `ForkJoinPool` with a fixed parallelism cap).\n- Or lower `vespera.direct.maxBufferBytes` to reduce per-thread allocation size.\n\n`DispatchMode.BIDIRECTIONAL_STREAMING` is safe for virtual threads and handles all payload sizes without pooling.\n\n---\n\n## 0.2.0 Breaking Changes\n\n### 1. Default DispatchModeResolver Flipped to SmartDispatchModeResolver\n\nPre-0.2.0 the autoconfigured default was `BidirectionalStreamingDispatchModeResolver` — every request that may carry a body streamed both ways, ~24.1 µs per round-trip uniform. Since 0.2.0 the default is `SmartDispatchModeResolver`.\n\n| Request shape | Pre-0.2.0 mode | 0.2.0+ mode |\n|---------------|----------------|-------------|\n| Small/bodyless idempotent (GET/HEAD/PUT/DELETE/OPTIONS, ≤ 256 KiB CL or no CL) | `STREAMING` / `BIDIRECTIONAL_STREAMING` | `DIRECT` |\n| Small non-idempotent (POST/PATCH, ≤ 256 KiB CL) | `BIDIRECTIONAL_STREAMING` | `SYNC` |\n| Large or unknown-length body | `BIDIRECTIONAL_STREAMING` | `BIDIRECTIONAL_STREAMING` |\n\nOpt out (restore the pre-0.2.0 default):\n\n```yaml\nvespera:\n bridge:\n dispatch-mode: bidirectional-streaming\n```\n\nOr register a custom `DispatchModeResolver` bean — `@ConditionalOnMissingBean` ensures it wins over both the property and the autoconfigured default.\n\n### 2. DecodedResponse.body() Returns ByteBuffer\n\n`DecodedResponse.body()` now returns a read-only `java.nio.ByteBuffer` (zero-copy view over the wire bytes). The owned `byte[]` materialisation moved to `DecodedResponse.bodyBytes()`.\n\n```java\n// Before 0.2.0\nbyte[] body = resp.body();\n\n// After 0.2.0\nbyte[] body = resp.bodyBytes(); // owned copy\nByteBuffer view = resp.body(); // zero-copy view\n```\n\nCallers that previously consumed `body()` as `byte[]` must switch to `bodyBytes()`.\n\n---\n\n## Migrating from the JSON-Envelope Bridge (≤ 0.0.13)\n\nThe pre-0.0.14 bridge used `dispatch(String) → String` with base64-encoded binary bodies.\n\n| Before | After |\n|--------|-------|\n| `VesperaBridge.dispatch(json)` | `encodeRequest(...)` → `dispatchBytes(...)` → `decodeResponse(...)` |\n| `body_bytes_b64` field on the response JSON | raw body bytes after the wire header (no base64) |\n| ~33% size overhead on binary bodies | zero overhead |\n\nExisting users of `VesperaProxyController` need no code change — the controller was rewritten to the new wire path internally. Direct callers of `VesperaBridge.dispatch(String)` must update; the old method was removed in 0.0.14.\n","title":"Streaming & Multi-App","url":"/documentation/theme/theme-3"}] \ No newline at end of file +[{"text":"# vespera!

Jobs are auto-discovered like routes — no extra registration needed.\n\n### Enable the Feature\n\n```toml\n[dependencies]\nvespera = { version = \"0.1\", features = [\"cron\"] }\n```\n\n### Define Jobs\n\nPlace `#[vespera::cron(\"...\")]` on any `pub async fn` with zero parameters. The function can live anywhere in your project:\n\n```rust\n// src/cron/cleanup.rs, src/tasks.rs, or even src/routes/users.rs — anywhere works\n#[vespera::cron(\"1/10 * * * * *\")]\npub async fn cleanup_sessions() {\n println!(\"Running cleanup every 10 seconds\");\n}\n\n#[vespera::cron(\"0 0 * * * *\")]\npub async fn hourly_report() {\n println!(\"Running hourly report\");\n}\n```\n\nNo extra config in `vespera!()` — jobs are discovered and started automatically:\n\n```rust\nlet app = vespera!(docs_url = \"/docs\");\n// Background scheduler starts when the app starts\n```\n\n### Cron Expression Format\n\nUses 6-field cron expressions (`sec min hour day month weekday`):\n\n| Expression | Schedule |\n|-----------|----------|\n| `0 */5 * * * *` | Every 5 minutes |\n| `0 0 * * * *` | Every hour |\n| `0 0 0 * * *` | Daily at midnight |\n| `1/10 * * * * *` | Every 10 seconds |\n| `0 30 9 * * Mon-Fri` | Weekdays at 9:30 AM |\n\n### Requirements\n\n- Functions must be `pub async fn`\n- Functions must take **no parameters** (no `State`, no extractors)\n- The `cron` feature must be enabled in `Cargo.toml`\n\n---\n\n## Multipart Form Data\n\n### Typed Multipart (Recommended)\n\nUse `TypedMultipart` for file uploads with a statically-known schema. Vespera generates `multipart/form-data` content type in OpenAPI and maps `FieldData` to `{ \"type\": \"string\", \"format\": \"binary\" }`:\n\n```rust\nuse vespera::multipart::{FieldData, TypedMultipart};\nuse vespera::{Multipart, Schema};\nuse tempfile::NamedTempFile;\n\n#[derive(Multipart, Schema)]\npub struct CreateUploadRequest {\n pub name: String,\n #[form_data(limit = \"10MiB\")]\n pub file: Option>,\n}\n\n#[vespera::route(post, tags = [\"uploads\"])]\npub async fn create_upload(\n TypedMultipart(req): TypedMultipart,\n) -> Json { ... }\n```\n\n### Raw Multipart (Untyped)\n\nFor dynamic fields not known at compile time, use Axum's built-in `Multipart` extractor. Vespera generates a generic `{ \"type\": \"object\" }` schema:\n\n```rust\nuse vespera::axum::extract::Multipart;\n\n#[vespera::route(post, tags = [\"uploads\"])]\npub async fn upload(mut multipart: Multipart) -> Json {\n while let Some(field) = multipart.next_field().await.unwrap() {\n let name = field.name().unwrap_or(\"unknown\").to_string();\n let data = field.bytes().await.unwrap();\n // Process each field dynamically...\n }\n Json(UploadResponse { success: true })\n}\n```\n\n---\n\n## Merging Multiple Vespera Apps\n\nCombine routes and OpenAPI specs from multiple crates at compile time. Useful for splitting a large API into separate crates while presenting a single unified spec.\n\n### Export a Child App\n\n```rust\n// In the child crate's src/lib.rs\nmod routes;\n\n// Export for merging (scans \"routes\" folder by default)\nvespera::export_app!(ThirdApp);\n\n// Or with a custom directory\nvespera::export_app!(ThirdApp, dir = \"api\");\n```\n\nThis generates:\n- `ThirdApp::OPENAPI_SPEC: &'static str` — the child's OpenAPI JSON\n- `ThirdApp::router() -> Router` — the child's Axum router\n\n### Merge in the Parent App\n\n```rust\nuse vespera::vespera;\n\nlet app = vespera!(\n openapi = \"openapi.json\",\n docs_url = \"/docs\",\n merge = [third::ThirdApp, other::OtherApp]\n)\n.with_state(app_state);\n```\n\nVespera automatically:\n- Merges all child routes into the parent router\n- Combines OpenAPI specs (paths, schemas, tags) into a single document\n- Makes Swagger UI show all routes from all apps\n\n---\n\n## Multi-App Routing (JNI)\n\nWhen embedding Vespera in a Java/Spring application via JNI, you can register multiple independent apps and route between them per request.\n\n```rust\npub fn create_app() -> axum::Router { vespera!(title = \"Default\") }\npub fn admin_app() -> axum::Router { vespera!(dir = \"admin_routes\", title = \"Admin\") }\npub fn public_app() -> axum::Router { vespera!(dir = \"public_routes\", title = \"Public\") }\n\nvespera::jni_apps! {\n \"_default\" => create_app,\n \"admin\" => admin_app,\n \"public\" => public_app,\n}\n```\n\nThe Java side selects an app per request via the `X-Vespera-App` header (configurable):\n\n```bash\n# Default app (no header)\ncurl http://localhost:8080/health\n\n# Admin app\ncurl -H \"X-Vespera-App: admin\" http://localhost:8080/dashboard\n```\n\nSee [Streaming & Multi-App](/documentation/theme/theme-3) for the full multi-app routing reference.\n","title":"Features","url":"/documentation/features"},{"text":"# Installation\n\nGet Vespera running in your Axum project in under five minutes.\n\n## 1.

      \n\nThe `direct_pooled` path completes a tiny `/health` round-trip in **2,349 ns/op** — **1.55× faster** than the pre-0.2.0 sync baseline (3,643 ns/op).\n\n## How It Works\n\n```\nsrc/routes/\n├── mod.rs → /\n├── users.rs → /users\n└── admin/\n └── stats.rs → /admin/stats\n```\n\n1. You place `pub async fn` handlers in `src/routes/` and annotate them with `#[vespera::route]`.\n2. The `vespera!()` macro scans the folder at compile time, discovers every handler, and builds an `axum::Router`.\n3. Types annotated with `#[derive(Schema)]` are extracted into OpenAPI component schemas automatically.\n4. The generated `openapi.json` and Swagger UI are served at the URLs you configure.\n\n## Get Started\n\nHead to [Installation](/documentation/installation) to add Vespera to your project in under five minutes.\n","title":"What is Vespera?","url":"/documentation/overview"},{"text":"# JNI / Java Integration\n\nVespera can embed your Axum router directly inside a Java/Spring application — no TCP socket, no JSON envelope overhead, raw bytes from end to end.\n\nThe `vespera-bridge` library (`kr.devfive:vespera-bridge`) provides a Spring Boot autoconfiguration that wires up a catch-all `VesperaProxyController`. Every HTTP request Spring receives is forwarded to Rust through a length-prefixed binary wire format, and the response comes back the same way.\n\n## Why In-Process?\n\nA traditional microservice setup adds a full HTTP round-trip between Java and Rust. In-process JNI dispatch eliminates that entirely:\n\n- No TCP connection overhead\n- No JSON serialization of the envelope\n- Binary bodies (multipart, PDFs, images) travel as raw bytes — no base64\n- Measured latency for small requests: **~2,200 ns** with the `DIRECT` dispatch mode\n\n## Quick Navigation\n\n- [jni_app! & VesperaBridge](/documentation/theme/theme-1) — Rust setup, Java setup, native library loading\n- [Dispatch Modes & Wire Format](/documentation/theme/theme-2) — all seven dispatch methods, binary wire layout, `SmartDispatchModeResolver` defaults\n- [Streaming & Multi-App](/documentation/theme/theme-3) — streaming tuning, multi-app routing, virtual thread notes, 0.2.0 breaking changes\n\n## Two-Line Integration\n\n**Rust side:**\n\n```rust\npub fn create_app() -> vespera::axum::Router {\n vespera!(title = \"My API\")\n}\n\nvespera::jni_app!(create_app);\n```\n\n**Java side:**\n\n```java\n@SpringBootApplication\n@ComponentScan(basePackages = {\"com.example.app\", \"com.devfive.vespera.bridge\"})\npublic class MyApp {\n public static void main(String[] args) {\n VesperaBridge.init(\"my_rust_lib\");\n SpringApplication.run(MyApp.class, args);\n }\n}\n```\n\nThat's it. `VesperaProxyController` is autoconfigured and forwards every HTTP request to Rust. Zero controller code, zero `application.yml` config, zero extra imports beyond the Spring Boot starter.\n","title":"JNI / Java Integration","url":"/documentation/theme"},{"text":"# jni_app! & VesperaBridge\n\n## Rust Setup\n\n### 1.

You write zero JNI code.\n\n### 3. Build as a cdylib\n\n```toml\n[lib]\ncrate-type = [\"cdylib\"]\n```\n\n```bash\ncargo build --release\n# Produces: target/release/libmy_rust_lib.so (Linux)\n# target/release/my_rust_lib.dll (Windows)\n# target/release/libmy_rust_lib.dylib (macOS)\n```\n\n---\n\n## Java Setup\n\n### Maven\n\n```xml\n\n kr.devfive\n vespera-bridge\n 0.2.0\n\n```\n\n### Gradle (Kotlin DSL)\n\n```kotlin\ndependencies {\n implementation(\"kr.devfive:vespera-bridge:0.2.0\")\n}\n```\n\n### Gradle Plugin (Recommended)\n\nThe `kr.devfive.vespera-bridge` Gradle plugin replaces ~22 lines of native-library-bundling boilerplate with a 5-line block:\n\n```kotlin\nplugins {\n id(\"kr.devfive.vespera-bridge\") version \"0.1.1\"\n}\n\nvespera {\n crateName.set(\"my_rust_lib\")\n cargoRoot.set(rootProject.layout.projectDirectory.dir(\"../..\"))\n bridgeVersion.set(\"0.2.0\")\n}\n```\n\nThe plugin auto-wires `bundleNativeLib` (cdylib → `resources/native/-/`), the `processResources` dependency, and the `vespera-bridge` implementation dependency.\n\n### Spring Boot Application\n\n```java\n@SpringBootApplication\n@ComponentScan(basePackages = {\"com.example.app\", \"com.devfive.vespera.bridge\"})\npublic class MyApp {\n public static void main(String[] args) {\n VesperaBridge.init(\"my_rust_lib\"); // loads cdylib (bundled or system path)\n SpringApplication.run(MyApp.class, args);\n }\n}\n```\n\n`VesperaProxyController` is autoconfigured via Spring Boot's `AutoConfiguration.imports`. It registers a `@RequestMapping(\"/**\")` catch-all that forwards every HTTP request to Rust. The routes published in Vespera's generated `openapi.json` are reachable at the same URLs through Spring.\n\n---\n\n## Native Library Loading\n\n`VesperaBridge.init(\"crateName\")` tries two paths in order:\n\n1. **Bundled** — looks up `native/{os}-{arch}/{libname}` inside the running JAR's classpath. If found, the file is extracted to a temp file (auto-deleted on JVM exit) and loaded via `System.load`.\n2. **Fallback** — `System.loadLibrary(\"crateName\")` searches `java.library.path`.\n\nSupported platform triples: `linux-x86_64`, `linux-aarch64`, `macos-x86_64`, `macos-aarch64`, `windows-x86_64`.\n\nPlace the cdylib at `src/main/resources/native/{os}-{arch}/` to bundle it inside the JAR for single-file deployment.\n\n---\n\n## Zero-Config Defaults\n\nOut of the box the autoconfigure module wires up:\n\n| Concern | Default | Override |\n|---------|---------|----------|\n| App selection | Read `X-Vespera-App` request header; absent → default app | Property `vespera.bridge.app-header`, or custom `AppNameResolver` bean |\n| Dispatch mode | `SmartDispatchModeResolver` since 0.2.0 — `DIRECT` for small/bodyless idempotent, `SYNC` for small non-idempotent, `BIDIRECTIONAL_STREAMING` for the rest | Property `vespera.bridge.dispatch-mode: bidirectional-streaming`, or custom `DispatchModeResolver` bean |\n| URL pattern | `@RequestMapping(\"/**\")` catch-all | Set `vespera.bridge.controller-enabled: false` and supply your own controller |\n\n---\n\n## Customization\n\n### Tweak via application.yml\n\n```yaml\nvespera:\n bridge:\n app-header: X-My-App # change the header that selects the app\n controller-enabled: true # set false to disable the proxy controller\n```\n\n### Custom App-Selection Strategy\n\n```java\n@Bean\npublic AppNameResolver myAppResolver() {\n return request -> {\n String uri = request.getRequestURI();\n if (uri.startsWith(\"/admin/\")) return \"admin\";\n if (uri.startsWith(\"/public/\")) return \"public\";\n return null; // default app\n };\n}\n```\n\nSpring's `@ConditionalOnMissingBean` automatically disables `HeaderAppNameResolver` when you supply your own bean.\n\n### Custom Dispatch-Mode Policy\n\n```java\n@Bean\npublic DispatchModeResolver myModeResolver() {\n return request -> {\n long contentLength = request.getContentLengthLong();\n if (contentLength >= 0 && contentLength < 4096\n && \"application/json\".equals(request.getContentType())) {\n return DispatchMode.SYNC;\n }\n return DispatchMode.BIDIRECTIONAL_STREAMING;\n };\n}\n```\n\n### BYO Controller\n\n```yaml\nvespera:\n bridge:\n controller-enabled: false\n```\n\n```java\n@RestController\npublic class MyController {\n @PostMapping(\"/api/admin/{path}\")\n public ResponseEntity adminRoute(@PathVariable String path, @RequestBody byte[] body) {\n byte[] wire = VesperaBridge.encodeRequest(\n \"admin\", \"POST\", \"/\" + path, null,\n Map.of(\"content-type\", \"application/json\"), body);\n byte[] resp = VesperaBridge.dispatchBytes(wire);\n DecodedResponse d = VesperaBridge.decodeResponse(resp);\n return ResponseEntity.status(d.status()).body(d.bodyBytes());\n }\n}\n```\n","title":"jni_app! & VesperaBridge","url":"/documentation/theme/theme-1"},{"text":"# Dispatch Modes & Wire Format\n\n## Binary Wire Format\n\nBoth request and response use the same length-prefixed layout:\n\n```\nbytes 0..4 : u32 BE = header_json byte length N\nbytes 4..4+N : UTF-8 JSON\n (request) { \"v\":1, \"method\", \"path\",\n \"query\"?, \"headers\"?

      \n\n### Choosing a Mode\n\n- Small JSON RPC, single request/response → `dispatchBytes`\n- Hot small/bounded payloads where JNI copy overhead matters → `dispatchDirect` / `dispatchDirectPooled`\n- Async I/O coordination (parallel Java requests, non-blocking) → `dispatchAsync` + `CompletableFuture`\n- Large download / streaming response (video, PDF, SSE) → `dispatchStreaming` + `OutputStream`\n- Large upload + large download (file transfer, video transcoding) → `dispatchFullStreaming` + `InputStream` + `OutputStream`\n- The `*WithHeader` variants let Spring-style controllers commit status/headers before the first body byte is written\n\n## SmartDispatchModeResolver (Default since 0.2.0)\n\nThe autoconfigured default since vespera-bridge 0.2.0 picks the cheapest safe path per request. Measured on a `GET /health` round-trip through the real JNI boundary:\n\n| Request shape | Mode | ns / round-trip |\n|---------------|------|-----------------|\n| Small/bodyless + idempotent (GET/HEAD/PUT/DELETE/OPTIONS, ≤ 256 KiB) | `DIRECT` | ~2,200 |\n| Small (≤ 256 KiB Content-Length) + non-idempotent (POST/PATCH) | `SYNC` | ~3,200 |\n| Large or unknown-length body | `BIDIRECTIONAL_STREAMING` | ~24,100 |\n\nTrade-offs:\n- **DIRECT** writes the wire response straight into a pooled per-thread direct `ByteBuffer` (64 KiB → `vespera.direct.maxBufferBytes`, default 4 MiB). Responses larger than the pooled buffer trigger a single retry that **re-runs the Rust handler** — which is why DIRECT is gated on idempotent methods only.\n- **SYNC** fully buffers the response on the JVM heap. The 256 KiB request-size gate keeps the response size reasonable for JSON-RPC-shaped traffic.\n- **BIDIRECTIONAL_STREAMING** is unchanged for large/unknown-length bodies — multi-GB upload + multi-GB download runs chunk-bounded, ~32 KiB resident each side.\n\nRestore the pre-0.2.0 default (every request that may carry a body streams both ways, ~24 µs uniform):\n\n```yaml\nvespera:\n bridge:\n dispatch-mode: bidirectional-streaming\n```\n\n## Direct Buffer Dispatch\n\n`dispatchDirect(ByteBuffer in, int inLen, ByteBuffer out)` eliminates the two JNI `GetByteArrayRegion`/`SetByteArrayRegion` copies that `dispatchBytes` pays. The response is streamed straight into the out buffer — no intermediate `Vec`. Measured at **1.4–3.4× per round-trip** versus `dispatchBytes` depending on payload size.\n\nContract:\n- Both buffers MUST be direct (`ByteBuffer.allocateDirect`); heap buffers are rejected with `IllegalArgumentException`\n- The request is read from absolute offsets `in[0..inLen]` — the buffer's position/limit are ignored; `inLen` is authoritative\n- Return `>= 0`: a complete wire response occupies `out[0..n]`\n- Return `< 0`: `-(requiredSize)` — the response did not fit; **retrying re-runs the Rust handler**, so only retry idempotent requests\n- `Integer.MIN_VALUE`: response exceeds 2 GiB\n\n`dispatchDirectPooled(byte[] wireRequest, boolean retryOnOverflow)` wraps the raw call with per-thread reusable direct buffers (64 KiB initial, doubling up to `vespera.direct.maxBufferBytes`, default 4 MiB).\n\n## Direct API (Without the Proxy Controller)\n\n```java\nimport com.devfive.vespera.bridge.VesperaBridge;\nimport com.devfive.vespera.bridge.VesperaBridge.DecodedResponse;\n\n// 1. Initialise once at startup\nVesperaBridge.init(\"my_rust_lib\");\n\n// 2. Encode a request\nbyte[] wireRequest = VesperaBridge.encodeRequest(\n \"POST\",\n \"/documents/validate\",\n /* query */ null,\n Map.of(\"content-type\", \"application/json\"),\n \"{\\\"title\\\":\\\"…\\\"}\".getBytes(StandardCharsets.UTF_8));\n\n// 3. Dispatch through Rust\nbyte[] wireResponse = VesperaBridge.dispatchBytes(wireRequest);\n\n// 4. Decode\nDecodedResponse resp = VesperaBridge.decodeResponse(wireResponse);\nSystem.out.println(resp.status()); // 200\nSystem.out.println(resp.headers()); // { \"content-type\": \"application/json\", … }\nSystem.out.println(new String(resp.bodyBytes())); // copies the raw response body\n```\n\n> **0.2.0 breaking change:** `DecodedResponse.body()` now returns a read-only `java.nio.ByteBuffer` (zero-copy view over the wire bytes). The owned `byte[]` materialisation moved to `DecodedResponse.bodyBytes()`. Callers that previously used `body()` as `byte[]` must switch to `bodyBytes()`.\n\n## Async Dispatch\n\n```java\nCompletableFuture future = VesperaBridge.dispatch(wireRequest);\n\nfuture.thenAccept(wireResponse -> {\n DecodedResponse resp = VesperaBridge.decodeResponse(wireResponse);\n System.out.println(\"Status: \" + resp.status());\n});\n```\n\nThe future is **always** completed with a valid wire response, even on Rust panics or JNI conversion failures. You will never see a dangling future.\n\n## Streaming Dispatch\n\n```java\nbyte[] wireRequest = VesperaBridge.encodeRequest(\n \"GET\", \"/files/large.pdf\", null, Map.of(), new byte[0]);\n\ntry (ByteArrayOutputStream sink = new ByteArrayOutputStream()) {\n byte[] headerOnly = VesperaBridge.dispatchStreaming(wireRequest, sink);\n DecodedResponse meta = VesperaBridge.decodeResponse(headerOnly);\n System.out.println(\"Status: \" + meta.status());\n System.out.println(\"Body size: \" + sink.size());\n}\n```\n\n## Bidirectional Streaming\n\n```java\ntry (InputStream upload = Files.newInputStream(Path.of(\"huge.mp4\"));\n OutputStream download = Files.newOutputStream(Path.of(\"transcoded.mp4\"))) {\n\n byte[] wireHeader = VesperaBridge.encodeRequestHeader(\n \"POST\", \"/transcode\", null,\n Map.of(\"content-type\", \"video/mp4\"));\n\n byte[] respHeader = VesperaBridge.dispatchFullStreaming(\n wireHeader, upload, download);\n\n DecodedResponse meta = VesperaBridge.decodeResponse(respHeader);\n System.out.println(\"Status: \" + meta.status());\n}\n```\n\nA 1 GiB upload paired with a 1 GiB download runs in low-single-digit MiB resident memory on each side. Backpressure is enforced naturally — if Axum reads slowly, `InputStream.read()` blocks on the bounded channel.\n","title":"Dispatch Modes & Wire Format","url":"/documentation/theme/theme-2"},{"text":"# Streaming & Multi-App\n\n## Streaming Tuning\n\nBoth streaming knobs are fixed for the process lifetime once the first dispatch runs. Configuration precedence (first hit wins):\n\n1. **Programmatic setter** — `VesperaBridge.configureStreaming(chunkBytes, channelCapacity)` (call before or after `init`)\n2. **System properties** — `vespera.streaming.chunkBytes`, `vespera.streaming.channelCapacity`\n3. **Environment variables** — `VESPERA_STREAMING_CHUNK_BYTES`, `VESPERA_STREAMING_CHANNEL_CAPACITY`\n4. **Built-in defaults** — 256 KiB chunk size, 16 channel slots\n\n| Setting | System property | Env var | Default | Range |\n|---------|----------------|---------|---------|-------|\n| Chunk buffer size | `vespera.streaming.chunkBytes` | `VESPERA_STREAMING_CHUNK_BYTES` | 256 KiB | 4 KiB – 8 MiB |\n| Request channel slots | `vespera.streaming.channelCapacity` | `VESPERA_STREAMING_CHANNEL_CAPACITY` | 16 | 1 – 1024 |\n| Tokio worker threads | `vespera.runtime.workerThreads` | `VESPERA_RUNTIME_WORKERS` | logical CPUs | 1 – 1024 |\n\n### Java API\n\nCall before `VesperaBridge.init(...)` for guaranteed precedence:\n\n```java\nVesperaBridge.configureStreaming(\n 131072, // chunkBytes: 128 KiB (clamped to 4 KiB – 8 MiB)\n 32 // channelCapacity: 32 slots (clamped to 1 – 1024)\n);\nVesperaBridge.init(\"my_rust_lib\");\n```\n\nWhen called before `init()`, values are stored as pending and applied immediately after the native library loads — before any dispatch can occur. This ensures the programmatic setter beats system properties and environment variables.\n\nThrows `IllegalArgumentException` if `chunkBytes` is outside `[4096, 8388608]` or `channelCapacity` is outside `[1, 1024]`.\n\n### System Properties\n\n```bash\njava -Dvespera.streaming.chunkBytes=131072 \\\n -Dvespera.streaming.channelCapacity=32 \\\n -jar app.jar\n```\n\n### Environment Variables\n\n```bash\nexport VESPERA_STREAMING_CHUNK_BYTES=131072\nexport VESPERA_STREAMING_CHANNEL_CAPACITY=32\njava -jar app.jar\n```\n\n### Tuning Tips\n\n- Larger chunks reduce the per-chunk JNI crossing cost (one `SetByteArrayRegion` + one `OutputStream.write` per chunk) at the price of per-stream memory. 256 KiB is a reasonable ceiling for throughput-oriented deployments.\n- The Tokio worker-thread knob caps Rust's shared runtime — useful when the JVM's own pools (Tomcat request threads, virtual-thread carriers) compete with Tokio for the same cores, or when a container CPU limit is lower than the host's logical CPU count.\n\n---\n\n## Multi-App Routing\n\nMulti-app routing is primarily a feature for external-dispatcher scenarios — JNI (Java host picks app per request via header), WebAssembly bridge, C FFI, or any in-process embedding where the host distinguishes between multiple independent Vespera API surfaces.\n\n### Rust Side\n\n```rust\npub fn create_app() -> axum::Router { vespera!(title = \"Default\") }\npub fn admin_app() -> axum::Router { vespera!(dir = \"admin_routes\", title = \"Admin\") }\npub fn public_app() -> axum::Router { vespera!(dir = \"public_routes\", title = \"Public\") }\n\nvespera::jni_apps! {\n \"_default\" => create_app,\n \"admin\" => admin_app,\n \"public\" => public_app,\n}\n```\n\n`jni_apps!` is the primary multi-app API. `jni_app!(create_app)` is syntactic sugar for a single default app.\n\n### Java Side\n\nThe default `HeaderAppNameResolver` selects an app per request via the `X-Vespera-App` header:\n\n```bash\n# Default app (no header)\ncurl http://localhost:8080/health\n\n# Admin app\ncurl -H \"X-Vespera-App: admin\" http://localhost:8080/dashboard\n\n# Public app\ncurl -H \"X-Vespera-App: public\" http://localhost:8080/info\n```\n\nEach app's URLs are independent — the same `/users` path can mean different things in `admin` vs `public` apps. Unknown app names return `404`; invalid app names (special characters, > 64 bytes) return `400`.\n\n### Custom App-Selection Strategy\n\n```java\n@Bean\npublic AppNameResolver myAppResolver() {\n // App name from the first path segment:\n // /admin/dashboard → app \"admin\", path \"/dashboard\"\n // /public/info → app \"public\", path \"/info\"\n return request -> {\n String uri = request.getRequestURI();\n if (uri.startsWith(\"/admin/\")) return \"admin\";\n if (uri.startsWith(\"/public/\")) return \"public\";\n return null; // default app\n };\n}\n```\n\n---\n\n## Virtual Thread (Project Loom) Limitation\n\nThe pooled direct-buffer methods (`dispatchDirectPooled`) use `ThreadLocal` to maintain per-thread reusable buffers. In Java 21+, `ThreadLocal` binds to the **virtual thread** (not the carrier thread) — so in a virtual-thread-per-request server, each virtual thread allocates a fresh direct buffer and loses all pooling benefit. Direct memory accumulates until the virtual thread is garbage-collected, potentially causing memory pressure under high concurrency.\n\n**Recommendations for virtual-thread deployments:**\n\n- Set `vespera.bridge.dispatch-mode=bidirectional-streaming` to opt out of the smart default, so `DIRECT` is never chosen by the autoconfigured resolver.\n- Or use `dispatchBytes`, `dispatchStreaming`, or `dispatchFullStreaming` directly instead of the pooled direct variants.\n- Or run dispatch on a bounded platform-thread executor (e.g. a `ForkJoinPool` with a fixed parallelism cap).\n- Or lower `vespera.direct.maxBufferBytes` to reduce per-thread allocation size.\n\n`DispatchMode.BIDIRECTIONAL_STREAMING` is safe for virtual threads and handles all payload sizes without pooling.\n\n---\n\n## 0.2.0 Breaking Changes\n\n### 1. Default DispatchModeResolver Flipped to SmartDispatchModeResolver\n\nPre-0.2.0 the autoconfigured default was `BidirectionalStreamingDispatchModeResolver` — every request that may carry a body streamed both ways, ~24.1 µs per round-trip uniform. Since 0.2.0 the default is `SmartDispatchModeResolver`.\n\n| Request shape | Pre-0.2.0 mode | 0.2.0+ mode |\n|---------------|----------------|-------------|\n| Small/bodyless idempotent (GET/HEAD/PUT/DELETE/OPTIONS, ≤ 256 KiB CL or no CL) | `STREAMING` / `BIDIRECTIONAL_STREAMING` | `DIRECT` |\n| Small non-idempotent (POST/PATCH, ≤ 256 KiB CL) | `BIDIRECTIONAL_STREAMING` | `SYNC` |\n| Large or unknown-length body | `BIDIRECTIONAL_STREAMING` | `BIDIRECTIONAL_STREAMING` |\n\nOpt out (restore the pre-0.2.0 default):\n\n```yaml\nvespera:\n bridge:\n dispatch-mode: bidirectional-streaming\n```\n\nOr register a custom `DispatchModeResolver` bean — `@ConditionalOnMissingBean` ensures it wins over both the property and the autoconfigured default.\n\n### 2. DecodedResponse.body() Returns ByteBuffer\n\n`DecodedResponse.body()` now returns a read-only `java.nio.ByteBuffer` (zero-copy view over the wire bytes). The owned `byte[]` materialisation moved to `DecodedResponse.bodyBytes()`.\n\n```java\n// Before 0.2.0\nbyte[] body = resp.body();\n\n// After 0.2.0\nbyte[] body = resp.bodyBytes(); // owned copy\nByteBuffer view = resp.body(); // zero-copy view\n```\n\nCallers that previously consumed `body()` as `byte[]` must switch to `bodyBytes()`.\n\n---\n\n## Migrating from the JSON-Envelope Bridge (≤ 0.0.13)\n\nThe pre-0.0.14 bridge used `dispatch(String) → String` with base64-encoded binary bodies.\n\n| Before | After |\n|--------|-------|\n| `VesperaBridge.dispatch(json)` | `encodeRequest(...)` → `dispatchBytes(...)` → `decodeResponse(...)` |\n| `body_bytes_b64` field on the response JSON | raw body bytes after the wire header (no base64) |\n| ~33% size overhead on binary bodies | zero overhead |\n\nExisting users of `VesperaProxyController` need no code change — the controller was rewritten to the new wire path internally. Direct callers of `VesperaBridge.dispatch(String)` must update; the old method was removed in 0.0.14.\n","title":"Streaming & Multi-App","url":"/documentation/theme/theme-3"}] \ No newline at end of file diff --git a/apps/landing/src/app/documentation/[...name]/theme.theme-3.mdx b/apps/landing/src/app/documentation/[...name]/theme.theme-3.mdx index 6305517e..2129c121 100644 --- a/apps/landing/src/app/documentation/[...name]/theme.theme-3.mdx +++ b/apps/landing/src/app/documentation/[...name]/theme.theme-3.mdx @@ -7,11 +7,11 @@ Both streaming knobs are fixed for the process lifetime once the first dispatch 1. **Programmatic setter** — `VesperaBridge.configureStreaming(chunkBytes, channelCapacity)` (call before or after `init`) 2. **System properties** — `vespera.streaming.chunkBytes`, `vespera.streaming.channelCapacity` 3. **Environment variables** — `VESPERA_STREAMING_CHUNK_BYTES`, `VESPERA_STREAMING_CHANNEL_CAPACITY` -4. **Built-in defaults** — 64 KiB chunk size, 16 channel slots +4. **Built-in defaults** — 256 KiB chunk size, 16 channel slots | Setting | System property | Env var | Default | Range | |---------|----------------|---------|---------|-------| -| Chunk buffer size | `vespera.streaming.chunkBytes` | `VESPERA_STREAMING_CHUNK_BYTES` | 64 KiB | 4 KiB – 8 MiB | +| Chunk buffer size | `vespera.streaming.chunkBytes` | `VESPERA_STREAMING_CHUNK_BYTES` | 256 KiB | 4 KiB – 8 MiB | | Request channel slots | `vespera.streaming.channelCapacity` | `VESPERA_STREAMING_CHANNEL_CAPACITY` | 16 | 1 – 1024 | | Tokio worker threads | `vespera.runtime.workerThreads` | `VESPERA_RUNTIME_WORKERS` | logical CPUs | 1 – 1024 | diff --git a/crates/vespera_inprocess/src/config.rs b/crates/vespera_inprocess/src/config.rs index 7acf06bc..ea69256f 100644 --- a/crates/vespera_inprocess/src/config.rs +++ b/crates/vespera_inprocess/src/config.rs @@ -5,12 +5,19 @@ use std::sync::OnceLock; // ── Streaming Configuration ────────────────────────────────────────── -/// Default per-chunk buffer size for streaming dispatches (64 KiB). +/// Default per-chunk buffer size for streaming dispatches (256 KiB). /// /// Large enough to amortise per-chunk FFI overhead (JNI region copy + /// `OutputStream.write` call per chunk), small enough to keep memory -/// bounded for multi-GB streams. -pub const DEFAULT_STREAMING_CHUNK_BYTES: usize = 64 * 1024; +/// bounded for multi-GB streams.

          Why calling-thread measurement captures the pooling win

          + * + *

          The streaming JNI entries + * ({@code Java_..._dispatchFullStreamingWithHeader} and friends in + * {@code crates/vespera_jni/src/jni_impl.rs}) allocate the Java byte[] chunk + * buffers via {@code env.new_byte_array(...)} on the JNI entry thread + * — i.e. the calling thread. Same for {@code set_region} / {@code get_region} + * on those arrays. Before TLS pooling those landed as fresh JVM allocations + * per dispatch; after pooling the same {@code GlobalRef} is + * reused across calls, so the calling-thread allocation count drops to + * effectively the request/response wire bytes plus a few small Java objects. + * + *

          Async caveat (honest)

          + * + *

          For {@code async_completable_future}, the {@code CompletableFuture} + * completion happens on a Rust Tokio worker thread (a daemon-attached + * cached worker), not the calling thread. This measurement therefore + * captures only what the caller pays: encoding the request, + * constructing the future, and {@code future.get()}-side allocations. + * Completion-side allocations on the daemon thread are not visible here + * and would require per-thread {@code getThreadAllocatedBytes} on the + * worker, which we don't observe by design. + * + *

The direct-buffer path (`dispatchDirect` + pooled `dispatchDirectPooled`, per-thread 64 KiB→4 MiB buffers via `vespera.direct.maxBufferBytes`) removes the two JNI region copies of `dispatchBytes`; on response overflow it returns `-(requiredSize)` and a retry **re-runs the handler**, so the Java side only auto-retries idempotent requests (`BufferTooSmallException` otherwise).
