RPCinterfaces
RPC interfaces define the surface of a remote service as seen by clients. They specify the available operations (methods), their input parameters, return values, and possible errors. The interface acts as a contract between client and server and is typically expressed in an interface description language (IDL). Tools generate client stubs and server skeletons from the interface definition, enabling code in multiple programming languages to interoperate.
Common RPC systems use different IDLs and protocols. Protocol Buffers with gRPC use .proto files to define
Key design concerns include data serialization, transport, and compatibility. Serialization converts in-memory values to a wire
RPC interfaces support synchronous and asynchronous patterns, streaming, and bidirectional streaming in some frameworks. They are
