Struct Duration 

pub struct Duration(/* private fields */);

A span of time, or a difference of two timestamps.

Arithmetic on durations is implemented as saturating.

Implementations

impl Duration

pub const ZERO: Duration

A zero-length duration.

pub fn abs(self) -> Duration

Absolute length of the duration, saturated.

pub fn as_seconds(self) -> f64

The length of the duration as a floating point number of seconds.

Note: Very large durations will loose precision when converted to a floating point.

pub fn as_raw_steps(self) -> i128

The length of the duration in steps (2^-64ths of a second)

pub fn as_nanos(self) -> i128

The length of the duration in nanoseconds, rounded.

pub fn from_raw_steps(steps: i128) -> Self

Create a duration from a length in steps (2^-64ths of a second)

pub fn log2(self) -> i8

Log2 length of the duration

pub fn from_f64_seconds(value: f64) -> Self

Create a duration from a floating point number of seconds.

Note: If the provided value is too large or too small to representable as a duration, the result will be clamped to the maximum or minimum respectively.

pub const fn from_seconds_nanos(seconds: i64, nanos: u32) -> Self

Create a duration from a given number of seconds, plus the given number of nanoseconds.

The nanoseconds are always applied in the positive direction, so for example from_seconds_nanos(-1, 500_000_000) represents minus half a second.
