Overview

GoogleRpcStatusUtils provides utilities to convert between a GRPC::Core::Status and a deserialized Google::Rpc::Status proto Returns nil if the grpc-status-details-bin trailer could not be converted to a GoogleRpcStatus due to the server not providing the necessary trailers. Raises an error if the server did provide the necessary trailers but they fail to deseriliaze into a GoogleRpcStatus protobuf.
