Question

我设法连接到TCP服务器并通过TCPStream发送问候消息。如果成功，我要返回TCPStream：

pub fn connect_to_tcpserver(&mut self) -> bool {
    let mut core = Core::new().unwrap();
    let handle = core.handle();

    let address = "127.0.0.1:2323".parse().expect("Unable to parse address");
    let connection = TcpStream::connect(&address, &handle);

    let client = connection.and_then(|mut tcp_stream| {
        tcp_stream.write(b"Hello");
        Ok(())
    });

    core.run(client).expect("Unable to run the event loop");

    return true;
}

在这种情况下如何返回tcp_stream变量？

AVDictionary *d = NULL; av_dict_set(&d, "foo", "bar", 0); frame->metadata = d;已经返回了Players = {0: "Quit", 1: "Player 1", 2: "Player 2", 3: "Player 3" } exits = {0: {"Q": 0}, 1: {"W": 2, "E": 3, "N": 5, "S": 4, "Q": 0}, 2: {"N": 5, "Q": 0}, 3: {"W": 1, "Q": 0}, 4: {"N": 1, "W": 2, "Q": 0}, 5: {"W": 2, "S": 1, "Q": 0}} avabilablePlayer = ",".join(list(Players.values())) print(avabilablePlayer) direction = input("Available Players are " + avabilablePlayer + " ").upper() player_index = None for key, value in Players.items(): if direction == value.upper(): player_index = key break if player_index is None: print('Invalid Player') else: dict_key = exits.get(player_index) print(dict_key)，所以我刚返回了

core.run
