函数 ctrl_break 

pub fn ctrl_break() -> Result<CtrlBreak>

创建一个新的监听器，用于接收发递给进程的 “ctrl-break” 通知。

示例

use tokio::signal::windows::ctrl_break;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // A listener of CTRL-BREAK events.
    let mut signal = ctrl_break()?;

    // Print whenever a CTRL-BREAK event is received.
    loop {
        signal.recv().await;
        println!("got signal CTRL-BREAK");
    }
}
