v0.13.0

New features 🎉

• Use context manager together with service handlers:

@contextvar
@asynccontextmanager
async def my_resource_manager():
    yield "hello"


@greeter.handler(invocation_context_managers=[my_resource_manager])
async def greet_with_cm(ctx: Context, name: str) -> str:
    return my_resource_manager.value

• Add msgspec support, works out of the box when adding restate_sdk[serde] dependency:

# models
class GreetingRequest(msgspec.Struct):
    name: str

class Greeting(msgspec.Struct):
    message: str

msgspec_greeter = Service("msgspec_greeter")

@msgspec_greeter.handler()
async def greet(ctx: Context, req: GreetingRequest) -> Greeting:
    return Greeting(message=f"Hello {req.name}!")

New features 🎉

• Added ingress client to send requests from your python applications to restate services:

async with restate.create_client("http://localhost:8080") as client:
  await client.object_call(increment, key="a", arg=5)
  await client.object_send(increment, key="a", arg=5)

  current_count = await client.object_call(count, key="a", arg=None)

• Added new test harness constructor to be used in combination with @pytest.fixture:

# Your fixture
@pytest.fixture(scope="session")
async def restate_test_harness():
  app = restate.app([greeter])
  async with restate.create_test_harness(app) as harness:
        yield harness
        
# A test example, using the client
async def test_greeter(restate_test_harness: HarnessEnvironment):
    greeting = await restate_test_harness.client.service_call(greet, arg="Pippo")
    assert greeting == "Hello Pippo!"
