impl Session for Chat {
    fn opened(&mut self, ctx: &mut SockJSContext<Self>) {
        ctx.broadcast("Someone joined.")
    }

impl Handler<Message> for Chat {
    type Result = ();

    fn handle(&mut self, msg: Message, ctx: &mut SockJSContext<Self>)
    {
        // broadcast message to all sessions
        ctx.broadcast(msg);
    }
}


fn main() {
