Module ticktock::timer

Interval-timer

Interval timers can be used to periodically perform an action or mutate a stored value. Values are owned by the timer itself, but can be retrieved.

The timer does not run in a separate thread, but rather expects to be triggered from the outside occasionally, with time being passed in usually to save on syscalls.

Example:

use std::time;
use ticktock::Timer;

let now = time::Instant::now();
let mut heartbeat = Timer::apply(
    |_, count| {
        *count += 1;
        *count
    },
    0,
)
.every(time::Duration::from_millis(500))
.start(now);

for i in 0..10 {
    let now = time::Instant::now();
    if let Some(n) = heartbeat.update(now) {
        println!("Heartbeat: {}", n);
    }
}
