Struct cap_primitives::time::Instant [−][src]
pub struct Instant { /* fields omitted */ }
Expand description
A measurement of a monotonically nondecreasing clock.
This corresponds to std::time::Instant
.
Note that this Instant
has no now
or elapsed
methods. To obtain the
current time or measure the duration to the current time, you must first
obtain a MonotonicClock
, and then call MonotonicClock::now
or
MonotonicClock::elapsed
instead.
Implementations
Constructs a new instance of Self
from the given
std::time::Instant
.
Returns the amount of time elapsed from another instant to this one.
This corresponds to std::time::Instant::duration_since
.
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
.
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
.
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
.
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
.
