Bump bytes from 1.6.0 to 1.11.1 in /rust

[dependabot]

Bumps bytes from 1.6.0 to 1.11.1 in the Rust workspace.

Problem

The original dependabot commit regenerated Cargo.lock using a newer version of Cargo that produced lock file format version 4. However, the CI uses nightly-2022-08-22 (Cargo 1.65), which only understands lock file format version 3. This caused the CI build to fail with:

error: failed to parse lock file at: rust/Cargo.lock
Caused by:
  lock file version `4` was found, but this version of Cargo does not understand this lock file, perhaps Cargo needs to be updated?

Fix

Downgraded the Cargo.lock version header from 4 back to 3. The lock file content is otherwise identical — no structural differences between v3 and v4 apply to this file. The bytes crate version remains correctly updated to 1.11.1.

Verification

Successfully built locally with nightly-2022-08-22:

cargo build --release --all-features --manifest-path rust/Cargo.toml
Finished release [optimized] target(s)

Fixes #21

Working session summary

The fix is complete. Here's what happened:

Root cause: The dependabot commit that bumped bytes from 1.6.0 to 1.11.1 regenerated rust/Cargo.lock using a newer version of Cargo, which produced lock file format version 4. However, the CI workflow uses the toolchain nightly-2022-08-22 (Cargo 1.65.0), which only understands lock file format version 3. This caused the "Build benchmark" CI step to fail immediately with a parse error.

Fix: Changed version = 4 back to version = 3 in rust/Cargo.lock. The actual content is identical — v4 format only adds optional new fields for entries, none of which exist in this file — so the downgrade is lossless. The bytes 1.11.1 version update is preserved.

Verified: Successfully built with the nightly-2022-08-22 toolchain locally before pushing.
