pub struct TCPClient<Q, A>where
    Q: SerializeMessage,
    A: SerializeMessage,{ /* private fields */ }

Messages can be any serializable object. This library uses a 9-byte header to encode the size of the serialized data sent and the result.

By default, postcard is used as wire serialization format
