Hjul is a thin wrapper around mio-extra timers. Example usage:
use hjul::Runner;
use std::thread;
use std::time::Duration;
let runner = Runner::new(Duration::from_millis(100), 100, 1024);
let timer = runner.timer(|| println!("fired"));
timer.start(Duration::from_millis(200));
// wait for timer to fire
thread::sleep(Duration::from_millis(500));
// start the timer again
timer.start(Duration::from_millis(200));
// stop timer immediately
timer.stop();
// start the timer again
timer.start(Duration::from_millis(200));
// timer is stopped when it goes out of scopeFull documentation at docs.rs/hjul
