CtrlC
A simple easy to use wrapper around Ctrl-C signal.
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.
