Struct coarsetime::Instant
source · pub struct Instant(_);
Expand description
A measurement of a monotonically increasing clock. Opaque and useful only with Duration
.
Implementations
sourceimpl Instant
impl Instant
sourcepub fn now() -> Instant
pub fn now() -> Instant
Returns an instant corresponding to “now”
This function also updates the stored instant.
sourcepub fn update()
pub fn update()
Update the stored instant
This function should be called frequently, for example in an event loop or using an
Updater
task.
sourcepub fn duration_since(&self, earlier: Instant) -> Duration
pub fn duration_since(&self, earlier: Instant) -> Duration
Returns the amount of time elapsed from another instant to this one
sourcepub fn elapsed_since_recent(&self) -> Duration
pub fn elapsed_since_recent(&self) -> Duration
Returns the amount of time elapsed between the this instant was created and the latest update
