v2.0.0-beta5

Enhancements

• Breaking: Client and Service Stubs no longer pack and unpack the input message fields as parameters #331:

  Update your client calls and server handlers as follows:

  Clients before:

  response = await service.echo(value="hello", extra_times=1)

  Clients after:

  response = await service.echo(EchoRequest(value="hello", extra_times=1))

  Servers before:

  async def echo(self, value: str, extra_times: int) -> EchoResponse: ...

  Servers after:

  async def echo(self, echo_request: EchoRequest) -> EchoResponse:
      # Use echo_request.value
      # Use echo_request.extra_times
      ...

• Format field comments also as docstrings #304

• Implement __deepcopy__ for Message #339

• Implement to/from_pydict() for Message #203

• Run isort on compiled code #355

• Expose timeout, deadline and metadata parameters from grpclib #352

• Make Message.__getattribute__ invisible to type checkers #359
