debounce

let debounce_fn = fns::debounce(|param: usize| {
  println!("{}", param);
}, std::time::Duration::from_secs(1));
debounce_fn.call(1); // skip
debounce_fn.call(2); // run after 1 second
// debounce_fn.terminate() // cancel call(2)

throttle

let throttle_fn = fns::throttle(|param: usize| {
  println!("{}", param);
}, std::time::Duration::from_secs(1));
throttle_fn.call(1); // run immediate
throttle_fn.call(2); // skip
throttle_fn.call(3); // last call will run after 1 second
// throttle_fn.terminate(); // cancel call(3)
