async-ctrlc

async-ctrlc is an async wrapper of the ctrlc crate.

Future example

use async_ctrlc::CtrlC;
use async_std::{prelude::FutureExt, task::sleep};
use std::time::Duration;

#[async_std::main]
async fn main() {
    let ctrlc = CtrlC::new().expect("cannot create Ctrl+C handler?");
    println!("Try to press Ctrl+C");
    ctrlc.race(async {
        let mut i = 0;
        loop {
            println!("... {}", i);
            sleep(Duration::from_secs(1)).await;
            i += 1;
        }
    }).await;
    println!("Quitting");
}

Stream example

use async_ctrlc::CtrlC;
use async_std::prelude::StreamExt as _;

#[async_std::main]
async fn main() {
    let ctrlc = CtrlC::new().expect("cannot create Ctrl+C handler?");
    println!("Try to press Ctrl+C 3 times");
    let mut stream = ctrlc.enumerate().take(3);
    while let Some((count, _)) = stream.next().await {
        println!("{} x Ctrl+C!", count + 1);
    }
    println!("Quitting");
}
