Struct CoarseDuration

pub struct CoarseDuration(Duration);

A duration with reduced precision, and, in the future, saturating arithmetic

This type represents a (nonnegative) period between two CoarseInstants.

This is (slightly lossily) interconvertible with std::time::Duration.

Range and precision

A CoarseDuration can represent at least 2^31 seconds, at a granularity of at least 1 second.

Panics

Currently, operations on CoarseDuration (including conversions) can panic on under/overflow. We regard this as a bug. The intent is that all operations will saturate.

impl Hash for CoarseDuration

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for CoarseDuration

fn cmp(&self, other: &CoarseDuration) -> 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,

impl PartialEq for CoarseDuration

fn eq(&self, other: &CoarseDuration) -> 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.

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.
