pub struct Instant { /* private fields */ }
Expand description
A measurement of a monotonically nondecreasing clock.
This corresponds to std::time::Instant
.
This Instant
has no now
or elapsed
methods. To obtain the current
time or measure the duration to the current time, first obtain a
MonotonicClock
, and then call MonotonicClock::now
or
MonotonicClock::elapsed
instead.
Implementations
sourceimpl Instant
impl Instant
sourcepub const fn from_std(std: Instant) -> Instant
pub const fn from_std(std: Instant) -> Instant
Constructs a new instance of Self
from the given
std::time::Instant
.
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.
This corresponds to std::time::Instant::duration_since
.
sourcepub fn checked_duration_since(&self, earlier: Instant) -> Option<Duration>
pub fn checked_duration_since(&self, earlier: Instant) -> Option<Duration>
Returns the amount of time elapsed from another instant to this one, or None if that instant is later than this one.
This corresponds to std::time::Instant::checked_duration_since
.
sourcepub fn saturating_duration_since(&self, earlier: Instant) -> Duration
pub fn saturating_duration_since(&self, earlier: Instant) -> Duration
Returns the amount of time elapsed from another instant to this one, or zero duration if that instant is later than this one.
This corresponds to std::time::Instant::saturating_duration_since
.
sourcepub fn checked_add(&self, duration: Duration) -> Option<Instant>
pub fn checked_add(&self, duration: Duration) -> Option<Instant>
Returns Some(t)
where t
is the time self + duration
if t
can be
represented as Instant
(which means it’s inside the bounds of the
underlying data structure), None
otherwise.
This corresponds to std::time::Instant::checked_add
.
sourcepub fn checked_sub(&self, duration: Duration) -> Option<Instant>
pub fn checked_sub(&self, duration: Duration) -> Option<Instant>
Returns Some(t)
where t
is the time self - duration
if t
can be
represented as Instant
(which means it’s inside the bounds of the
underlying data structure), None
otherwise.
This corresponds to std::time::Instant::checked_sub
.
