函数 ctrl_shutdown 

pub fn ctrl_shutdown() -> Result<CtrlShutdown>

创建一个新的监听器，用于接收发递给进程的 “ctrl-shutdown” 通知。

示例

use tokio::signal::windows::ctrl_shutdown;

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

    signal.recv().await;
    println!("got CTRL-SHUTDOWN. Cleaning up before exiting");

    Ok(())
}
