Struct SleepFuture 

pub struct SleepFuture { /* private fields */ }

A future that completes after a given duration.

Created by sleep. On first poll it registers a timer with the executor and computes a deadline. Subsequent polls check the deadline — this makes the future robust against premature re-polls (e.g. from select! or executor wake-ups unrelated to the timer).

Trait Implementations

impl Future for SleepFuture

type Output = ()

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, _cx: &mut Context<'_>) -> Poll<()>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
