Function tokio::time::delay_for

Important traits for Delay

impl Future for Delay type Output = ();

pub fn delay_for(duration: Duration) -> Delay

This is supported on feature="time" only.

Wait until duration has elapsed.

Equivalent to delay_until(Instant::now() + duration). An asynchronous analog to std::thread::sleep.

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.
