Struct SignedDuration 

pub struct SignedDuration { /* private fields */ }

Signed nanosecond-backed duration used for derived timing values.

This type preserves negative values that can arise after subtracting server processing time or comparing wall-clock timestamps from different hosts. It should not be used to represent raw elapsed wall-clock or monotonic time, which is non-negative and represented by Duration.

Implementations

impl SignedDuration

pub const fn from_nanos(ns: i128) -> Self

Construct a signed duration from nanoseconds.

pub fn from_duration(duration: Duration) -> Self

Convert a non-negative Duration into a signed duration.

Durations larger than i128::MAX nanoseconds saturate to i128::MAX.

pub const fn as_nanos(self) -> i128

Return the duration in nanoseconds.

pub const fn as_micros(self) -> i128

Return the duration in whole microseconds, truncated toward zero.

pub const fn as_millis(self) -> i128

Return the duration in whole milliseconds, truncated toward zero.

pub const fn is_negative(self) -> bool

Return whether this duration is less than zero.

Trait Implementations

impl Clone for SignedDuration

fn clone(&self) -> SignedDuration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SignedDuration

impl Debug for SignedDuration

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

Formats the value using the given formatter.

impl Eq for SignedDuration

impl From<Duration> for SignedDuration

fn from(value: Duration) -> Self

Converts to this type from the input type.

impl Ord for SignedDuration

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

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

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