我有一个启动工作线程的线程,所有线程都应该永远存在.每个工作线程都维护着自己的Sockets 列表.

有些操作要求我遍历当前活动的所有套接字,但是我在尝试创建包含指向另一个列表所拥有的套接字的指针的套接字的主列表时遇到了麻烦.

use std::{str, thread};
use std::thread::JoinHandle;
use std::io::{Read, Write};
use std::net::{TcpListener, TcpStream};
use std::sync::{Arc, Mutex};
use std::ops::DerefMut;
use std::sync::mpsc::{channel, Sender, Receiver, TryRecvError};
use self::socketlist::SocketList;
use self::mastersocketlist::MasterSocketList;

pub struct Socket {
    user: String,
    stream: TcpStream,
}

mod socketlist {
    use self::SocketList::{Node, End};
    use super::Socket;

    pub enum SocketList {
        Node(Socket, Box<SocketList>),
        End,
    }

    impl SocketList {
        pub fn new() -> SocketList {
            End
        }

        pub fn add(self, socket: Socket) -> SocketList {
            Node(socket, Box::new(self))
        }

        pub fn newest<'a>(&'a …
