Enum TimerDuration 

pub enum TimerDuration {
    Elapsed,
    Real(Duration),
    Infinite,
}

A duration wrapper supporting elapsed/negative, real, and infinite durations. Due to the solar system’s impending collapse before the 64 bit integer limit of seconds is reached, an Infinite duration is translated to that when turning this back info a normal duration. If you run your program for longer than the sun’s entire lifespan including the past, this may cause an issue. But I think you’ll have much bigger issues long before that, including the fact that you even came up with that idea.

Variants

Elapsed

Real(Duration)

Infinite

Implementations

impl TimerDuration

pub fn from_difference(a: TimerDuration, b: Duration) -> TimerDuration

Takes the difference between a TimerDuration a and a Duration b, resulting in either a negative (Elapsed) duration or a Real one. The Infinite duration is passed through as-is, with no subtraction done to it.

pub fn to_real(&self) -> Duration

Converts this into a Duration that is waitable by rust’s standard functions, for use in e.g. specifying timeouts to std operations.

pub const fn is_elapsed(&self) -> bool

pub const fn is_real(&self) -> bool

pub const fn is_infinite(&self) -> bool

Trait Implementations

impl Clone for TimerDuration

fn clone(&self) -> TimerDuration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl From<Duration> for TimerDuration

fn from(value: Duration) -> Self

Converts to this type from the input type.

impl From<u64> for TimerDuration

fn from(value: u64) -> Self

Converts to this type from the input type.

impl Ord for TimerDuration

fn cmp(&self, other: &Self) -> 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 TimerDuration

fn eq(&self, other: &TimerDuration) -> 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 TimerDuration

fn partial_cmp(&self, other: &Self) -> 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.
