Function tokio::time::delay_until

Important traits for Delay

impl Future for Delay type Output = ();

pub fn delay_until(deadline: Instant) -> Delay

This is supported on feature="time" only.

Waits until deadline is reached.

No work is performed while awaiting on the delay to complete. The delay operates at millisecond granularity and should not be used for tasks that require high-resolution timers.

Cancellation

Canceling a delay is done by dropping the returned future. No additional cleanup work is required.
