Struct Interval 

pub struct Interval { /* private fields */ }

A periodic timer. Each call to tick() returns a future that resolves at the next scheduled instant.

Deadlines are fixed-period (next = prev + period), not floating (next = now + period), so accumulated drift is O(1) not O(n).

Created by interval().

ctx.spawn(async move {
    let mut frame_timer = interval(Duration::from_millis(16));
    loop {
        frame_timer.tick().await;
        update_animation();
    }
});

Implementations

impl Interval

pub fn tick(&mut self) -> Sleep

Wait until the next tick.

Returns a Sleep future targeting the pre-computed deadline, then advances the deadline by one period.
