pub struct DInstant(/* private fields */);
Expand description

Duration elapsed since an epoch.

By default this is the duration elapsed since the first usage of INSTANT in the process.

Implementations§

source§

impl DInstant

source

pub const EPOCH: DInstant = _

Earliest instant.

source

source

pub fn elapsed(self) -> Duration

Returns the amount of time elapsed since this instant.

source

pub fn duration_since(self, earlier: DInstant) -> Duration

Returns the amount of time elapsed from another instant to this one, or zero duration if that instant is later than this one.

source

pub fn checked_add(&self, duration: Duration) -> Option<DInstant>

Returns Some(t) where t is the time self + duration if t can be represented.

source

pub fn checked_sub(self, duration: Duration) -> Option<DInstant>

Returns Some(t)`` where t is the time self - durationifduration` greater then the elapsed time since the process start.

source

pub fn checked_duration_since(&self, earlier: DInstant) -> Option<Duration>
