Struct Instant

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

A measurement of a monotonically nondecreasing clock.

Implementations

impl Instant

pub fn now() -> Self

Returns the current monotonic time.

pub fn elapsed(&self) -> Duration

Returns the amount of time elapsed since this instant.

Prefer secs_f64_since() if used for metrics.

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

Returns the amount of time elapsed from another instant to this one.

This method saturates to zero.

pub fn secs_f64_since(&self, earlier: Self) -> f64

Returns the number of seconds elapsed from another instant to this one.

This method saturates to zero.

pub fn nanos_since(&self, earlier: Self) -> u64

Returns the number of nanosecs elapsed from another instant to this one.

This method saturates to zero.

Trait Implementations

impl Clone for Instant

fn clone(&self) -> Instant

Returns a duplicate 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,

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.
