Struct cap_async_std::time::Instant

[+] Show declaration

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

impl Instant[−]

pub const fn from_std(std: Instant) -> Instant[−]

Constructs a new instance of Self from the given std::time::Instant.

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.

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.

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.

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.

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.

Trait Implementations

impl Add<Duration> for Instant[+]

type Output = Instant
