Function async_timer 

pub fn async_timer(task: CTimerCB, interval: u64) -> CTimerResult

Creates a repeating CTimerCB on the specified interval (in milliseconds). The task is completed when the CTimerResult::stop is called.

Example:

fn timer_cb() {
  println!("Hello");
}

let timer_task = codemelted::async_timer( timer_cb, 250);
codemelted::async_sleep(100);
assert!(timer_task.is_running());
codemelted::async_sleep(1000);
timer_task.stop();
assert!(!timer_task.is_running());
