Struct Instant 

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

A point in time on the clock of the runtime the code runs in.

It is std’s Instant as long as the runtime’s clock runs as the system’s; pause stops it and advance moves it, and every timer follows it. The two convert both ways (from_std, into_std).

Implementations

impl Instant

pub fn now() -> Self

The time now on the runtime’s clock.

pub fn from_std(std: Instant) -> Self

The instant std names.

pub fn into_std(self) -> Instant

This instant as std’s.

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

The time from earlier to this instant, zero if earlier is later.

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

The time from earlier to this instant, None if earlier is later.

pub fn saturating_duration_since(&self, earlier: Self) -> Duration

The time from earlier to this instant, zero if earlier is later.

pub fn elapsed(&self) -> Duration

The time on the runtime’s clock since this instant.

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

This instant moved forward by duration, None past the clock’s range.

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

This instant moved back by duration, None before the clock’s range.
