TCPListenNotify

[Source]

Callbacks for a TCP listener. Implement this trait and pass it to TCPListener to handle listener events.

on_connected and on_not_listening have no default implementations. on_connected is where you create the notifier for each accepted connection. on_not_listening must be implemented because ignoring a listen failure silently is never correct.
