pub struct Sleep { /* private fields */ }
Expand description
Future returned by sleep
and sleep_until
.
Implementations
sourceimpl Sleep
impl Sleep
sourcepub fn is_elapsed(&self) -> bool
pub fn is_elapsed(&self) -> bool
Returns true
if Sleep
has elapsed.
A Sleep
instance is elapsed when the requested duration has elapsed.
sourcepub fn reset(&mut self, deadline: Instant)
pub fn reset(&mut self, deadline: Instant)
Resets the Sleep
instance to a new deadline.
Calling this function allows changing the instant at which the Sleep
future completes without having to create new associated state.
This function can be called both before and after the future has completed.
