Documentation

Example usage

In cargo.toml:

[dependencies]
ctrlc = "3.4"

then, in main.rs

use std::sync::mpsc::channel;
use ctrlc;

fn main() {
    let (tx, rx) = channel();
    
    ctrlc::set_handler(move || tx.send(()).expect("Could not send signal on channel."))
        .expect("Error setting Ctrl-C handler");
    
    println!("Waiting for Ctrl-C...");
    rx.recv().expect("Could not receive from channel.");
    println!("Got it! Exiting..."); 
}

Try the example yourself

cargo build --examples && target/debug/examples/readme_example

Handling SIGTERM and SIGHUP

Add CtrlC to Cargo.toml using termination feature and CtrlC will handle SIGINT, SIGTERM and SIGHUP.
