How to join/leave a socket.io room

[1c3t3a]

Hi, thanks for using the crate! You're right, there are no functions concerning rooms, but that's because this crate currently only implements the client and rooms is a fully server side feature. That means managing rooms in any way is done on the server side, a client does not have any information about which room he's in or even which rooms exist on the server side. For further reading visit the official socket.io documentation. An example using this client would look something like this:

server code

// assume you've set up the server somehow
io.on('connection', function(socket) {
    // you can join (leave) a room by calling the join (leave) method
    socket.on('room', function(room) {
        socket.join(room);
    });
});

// this emits to all clients in the room
io.sockets.in("room1").emit('message', 'what is going on, party people?');

client code

use serde_json::json;
// ...
// assume you've connected the client and defined callbacks for certain events
let payload = json!("room1");
socket.emit("room", payload).expect("Server unreachable");

I see, rust-socketio is only a client crate.

Thanks a lot. @1c3t3a

Do you have any plan to implement socketio server side features?

Actually yes, there is a tracking issue for this (#32). I will tackle it as soon as possible, but if you're interested, feel free to implement it ;)
