First of all, sorry if I'm missing something obvious. I'm trying to figure out if an instance of a UdpSocket has been connect-ed or not (and in extension, to which ip+port).
My use case is that I have a thread that's responsible for listening for packets and responding to them. Prior to starting this thread, I might or might not have been told from which ip+port the packets will originate from. So my setup code looks something like this:
let socket = UdpSocket::bind("0.0.0.0:0").unwrap();
if was_told_remote_port {
socket.connect((remote_addr, remote_port)).unwrap();
}
spawn_worker_with_socket(socket);
If we weren't told the port, we'll simply wait for the first packet, and then connect to that port. The worker thus looks something like this:
// FIXME: look if the socket is already connected
let mut connected = false;
loop {
let mut buffer: [u8; 200] = [0; 200];
if connected {
socket.recv(&mut buffer).unwrap();
} else {
let (_, sender) = socket.recv_from(&mut buffer).unwrap();
socket.connect(sender).unwrap();
connected = true;
}
// ...
}
Now, in this simplified example, it would be really easy to just pass was_told_remote_port to the worker. But in my large codebase, it would help a lot if this state could be accessed directly from the socket since it must be stored there already somehow (right?).
Thanks!
