Function delay_for

pub fn delay_for(duration: Duration) -> Delay 

Available on crate 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.
