我当前使用bytes板条箱的代码：

pub async fn send_msg(online_users: Arc<Mutex<OnlineUsers>>, msg: &Message, from: &str) -> io::Result<()> {
    let target_user = msg.args.get(0).ok_or(io::Error::from(io::ErrorKind::InvalidInput))?;
    if let Content::Text(ref text) = msg.content {
        let text_owned = text.clone();
        let text_byte = Bytes::from(text_owned.as_bytes());
        let mut online_users = online_users.lock().await;
        online_users.send_to_user(target_user, text_byte).await; 
    }
    Ok(())
}

错误发生在send_to_user（）调用处，其定义为：

pub async fn send_to_user(&mut self, name: &str, content: Bytes) -> io::Result<()> {
    let target_user = self
        .list
        .get_mut(name)
        .ok_or(io::Error::new(io::ErrorKind::NotConnected, name.clone()))?;
    target_user.send(content).await?;
    Ok(())
}

错误消息如下：

error[E0597]: `text_owned` does not live long enough
  --> server/src/handler.rs:28:37

28 |         let text_byte = Bytes::from(text_owned.as_bytes());
   |                         ------------^^^^^^^^^^^^^^^^^^^^^-

...
31 |     }
   |     - `text_owned` dropped here while still borrowed

我不明白为什么它的寿命不够长。因为我在send_to_user()上调用了. wait，所以它必须在send_msg()到达其结尾并删除所有变量之前完成。我希望：
1.解释为什么会这样。
1.我该怎么补救呢？
