Can PEP compliant type hints be automatically added to generated source code, or dynamically created, for python and gRPC? Specifically in the basics tutorial in the client section for feature = stub.GetFeature(point) I would like my IDE to know and check that point is type Point in the *_pb2.py and feature is type Feature with an attribute location: Point. Thank you.
Type hints aren't yet (!?) available for Python gRPC, see Issue 29041
You can generate type hints for the Protobuf messages only using the --pyi_out=${PWD} flag when running protoc directly or indirectly with python3 -m grpc.tools.protoc
