Struct SignalGuard 

pub struct SignalGuard(/* private fields */);

Implementations

impl SignalGuard

pub fn new() -> SignalGuard

Block necessary signals (SIGINT, SIGQUIT and SIGTERM on *nix, Ctrl+C and Ctrl+Break on Windows).

New threads should be spawned after this.

Examples found in repository

examples/simple.rs (line 17)

fn main() {
  let signal_guard = SignalGuard::new();

  let handle = thread::spawn(|| {
    println!("Worker thread started. Type Ctrl+C to stop.");
    while !STOP.load(Ordering::Acquire) {
      println!("working...");
      thread::sleep(Duration::from_millis(500));
    }
    println!("Bye.");
  });

  signal_guard.at_exit(move |sig| {
    println!("Signal {} received.", sig);
    STOP.store(true, Ordering::Release);
    handle.join().unwrap();
  });
}

pub fn at_exit<F: FnOnce(usize)>(&self, handler: F)

Block the running thread until a signal is received. Then the handler will be called in the main thread.

Do not put any code after this.
