Struct rtfm::Instant

pub struct Instant(_);

A measurement of a monotonically nondecreasing clock. Opaque and useful only with Duration

This data type is only available when the timer-queue feature is enabled

Methods

impl Instant

pub fn now() -> Self

Returns an instant corresponding to "now"

pub fn elapsed(&self) -> Duration

Returns the amount of time elapsed since this instant was created.

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

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

Trait Implementations

impl PartialEq<Instant> for Instant

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Eq for Instant

impl Ord for Instant

fn cmp(&self, rhs: &Self) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialOrd<Instant> for Instant

fn partial_cmp(&self, rhs: &Self) -> Option<Ordering>

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

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.
