Struct Delta

pub struct Delta { /* private fields */ }

A span of time.

This struct represents a span of time, with its value stored as nanoseconds. The value can represent any valid i64 value, including negative, zero, and positive numbers.

Implementations

impl Delta

pub const ZERO: Self

A span of time equal to zero.

pub const fn from_micros(micros: i64) -> Self

Create a new Delta from a number of microseconds.

The micros can range from -9_223_372_036_854_775 to 9_223_372_036_854_775. If micros is outside this range, i64::MIN is used for negative values, and i64::MAX is used for positive values due to saturation.

pub const fn from_millis(millis: i64) -> Self

Create a new Delta from a number of milliseconds.

The millis can range from -9_223_372_036_854 to 9_223_372_036_854. If millis is outside this range, i64::MIN is used for negative values, and i64::MAX is used for positive values due to saturation.

pub const fn from_secs(secs: i64) -> Self

Create a new Delta from a number of seconds.

The secs can range from -9_223_372_036 to 9_223_372_036. If secs is outside this range, i64::MIN is used for negative values, and i64::MAX is used for positive values due to saturation.

pub fn is_zero(self) -> bool

Return true if the Delta spans no time.

pub fn is_negative(self) -> bool

Return true if the Delta spans a negative amount of time.

pub const fn as_nanos(self) -> i64

Return the number of nanoseconds in the Delta.

pub const fn as_micros_ceil(self) -> i64

Return the smallest number of microseconds greater than or equal to the value in the Delta.

pub const fn as_millis(self) -> i64

Return the number of milliseconds in the Delta.

Trait Implementations

impl Clone for Delta

fn clone(&self) -> Delta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Delta

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

Formats the value using the given formatter.

impl Ord for Delta

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

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

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