Struct pal_async::timer::Instant

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

Instant represents a number of nanoseconds since some process-specific epoch.

On Windows this is backed by QueryUnbiasedInterruptTimePrecise. On Linux this is backed by CLOCK_MONOTONIC.

This is modeled after std::time::Instant but uses a different clock source on Windows, and it allows access to the raw value.

Implementations

impl Instant

pub fn now() -> Self

The current time as measured by this clock.

pub fn as_nanos(&self) -> u64

Returns the value of the underlying clock in nanosecond resolution.

pub fn from_nanos(nanos: u64) -> Self

Creates an instant from an underlying clock value in nanosecond resolution.

pub fn saturating_add(self, duration: Duration) -> Self

Adds a duration to this instant, saturating at the maximum value of the clock.

Trait Implementations

impl Add<Duration> for Instant

type Output = Instant

The resulting type after applying the + operator.

fn add(self, rhs: Duration) -> Self::Output

Performs the + operation.

impl Clone for Instant

fn clone(&self) -> Instant

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Instant

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Ord for Instant

fn cmp(&self, other: &Instant) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Instant

fn eq(&self, other: &Instant) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Instant

fn partial_cmp(&self, other: &Instant) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Sub<Duration> for Instant

type Output = Instant

The resulting type after applying the - operator.

fn sub(self, rhs: Duration) -> Self::Output

Performs the - operation.

impl Sub for Instant

type Output = Duration

The resulting type after applying the - operator.

fn sub(self, rhs: Instant) -> Self::Output

Performs the - operation.
