我是Rust的新手，我正在实现一个简单的客户端服务器应用程序。我设法让应用程序从std：：sync：：TcpStream库工作。现在我希望服务器能够使用时雄库异步地接受请求。应用程序的操作基于两种类型的客户端，写入器和读取器。写入器将通过tcp流写入服务器，读取器将阅读服务器上的内容。为了在服务器上建立内部连接，我使用时雄通道。
当我试图通过参数将我创建的通道的发送者和接收者传递给处理流的函数时，我遇到的问题是相关的。
这里是代码。我想我真的不明白变量引用在rust中是如何工作的。

use tokio::net::TcpListener;
use tokio::net::TcpStream;
use tokio::sync::mpsc;
use tokio::sync::mpsc::{Sender, Receiver};
use std::error::Error;

async fn handle_connection(mut stream: TcpStream, sender: &Sender<[u8; 128]>, receiver: &Receiver<[u8; 128]>) -> Result<(), Box<dyn Error>> {
    
    //do something...
        
}

pub async fn create_listener(addr: String) -> Result<(), Box<dyn Error>> {

    let listener = TcpListener::bind(&addr).await?;

    let (sender, receiver) = mpsc::channel(10);

    loop {
        let (mut stream, _) = listener.accept().await?;

        tokio::spawn(async move {
            handle_connection(stream, &sender, &receiver);
        });
    }

    Ok(())
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {

    create_listener(String::from("127.0.0.1:8000")).await?;

    Ok(())

}

返回的错误如下：

你能解释一下为什么会这样吗？怎么解决？
