# [−] [src] Function tokio::time::interval_at

    pub fn interval_at(start: Instant, period: Duration) -> Interval

Creates new `Interval` that yields with interval of `period` with the first tick completing at `start`.

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]
    async fn main() {
        let start = Instant::now() + Duration::from_millis(50);
        let mut interval = interval_at(start, Duration::from_millis(10));

        interval.tick().await;
        interval.tick().await;
        interval.tick().await;

        // approximately 70ms have elapsed.
    }
