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}!")
