   - A {ruby Protocol::GRPC::Interface} class which defines gRPC service contracts with RPC methods, request/response types, and streaming patterns.
-  - A {ruby Protocol::GRPC::Body::ReadableBody} class which handles reading gRPC messages from HTTP request/response bodies with automatic framing and decoding.

   - A {ruby Protocol::GRPC::Middleware} abstract base class for building gRPC server applications.
   - A {ruby Protocol::GRPC::Call} class which represents the context of a single gRPC RPC call, including deadline tracking.
   - A {ruby Protocol::GRPC::Status} module with gRPC status code constants.
