Creates new Interval that yields with interval of period with the first tick completing at start. The default MissedTickBehavior is Burst, but this can be configured by calling set_missed_tick_behavior.

An interval will tick indefinitely. At any time, the Interval value can be dropped. This cancels the interval.

Panics

This function panics if period is zero.

Examples

use tokio::time::{interval_at, Duration, Instant};

# #[tokio::main(flavor = "current_thread")]
# async fn main() {
let start = Instant::now() + Duration::from_millis(50);
let mut interval = interval_at(start, Duration::from_millis(10));

interval.tick().await; // ticks after 50ms
interval.tick().await; // ticks after 10ms
interval.tick().await; // ticks after 10ms

// approximately 70ms have elapsed.
# }
