pub async fn bind(addr: SocketAddr) -> Result<TcpListener>Expand description
Bind a TCP listener on addr. Pass a port of 0 to let the OS pick
a free port; read it back from TcpListener::local_addr.
Exposed as a free function (rather than an associated function on
the generic ControlServer) so callers do not need a turbofish
to pin the handle type before they own a state value.
