The code requires cc_generic_services = true in the service proto files. nng_msg payload is: request format : size:u32 + serialized MethodCall response format: size:u32 + serialized MethodCallResponse Dispatch is done using descriptors, message prototypes and protobuf.Any. Error handling is missing apart from error logging.
