Expand description

An object implementing this trait handles TCP connections in a Future.

The caller would ask the service to handle() the anaccepted io stream and connection (most likely a TcpStream, but abstracted for testability), then poll the returned future to completion. The service may chose to block on the call, effectively preventing concurrent connections, or better to spawn into background and return immediately so that other connections can be received. It could also push back on accepting more connections if it notices too many connections or another resource shortage by blocking on the handle() call.

The SmtpService and DummyService implement this trait.
