Crate signalbool [−] [src]
A simple crate to catch signals and set a boolean flag for later use.
This crate doesn't create threads behind the scene.
Example
Here is a program that sleeps until it receives three SIGINT
signals.
extern crate signalbool; extern crate nix; use nix::unistd::sleep; fn main() { let mut sb = signalbool::SignalBool::new( &[signalbool::Signal::SIGINT], signalbool::Flag::Interrupt, ).unwrap(); let mut count = 0; loop { sleep(10); if sb.caught() { println!("Caught SIGINT."); count += 1; sb.reset(); if count == 3 { break; } } } }
