Struct zng_app::DInstant

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

Duration elapsed since an epoch.

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

Implementations

impl DInstant

pub fn elapsed(self) -> Duration

Returns the amount of time elapsed since this instant.

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.

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

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

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.

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

Returns the amount of time elapsed from another instant to this one, or None if that instant is later than this one.

pub fn saturating_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.

pub const EPOCH: DInstant = _

Earliest instant.

pub const MAX: DInstant = _

The maximum representable instant.
