Struct tokio::time::Delay

#[must_use = "futures do nothing unless you `.await` or poll them"]pub struct Delay { /* fields omitted */ }

This is supported on crate feature time only.

Future returned by delay_until and delay_for.

Implementations

impl Delay

pub fn deadline(&self) -> Instant

Returns the instant at which the future will complete.

pub fn is_elapsed(&self) -> bool

Returns true if the Delay has elapsed

A Delay is elapsed when the requested duration has elapsed.

pub fn reset(&mut self, deadline: Instant)

Resets the Delay instance to a new deadline.

Calling this function allows changing the instant at which the Delay future completes without having to create new associated state.

This function can be called both before and after the future has completed.
