Struct Duration

pub struct Duration {
    seconds: i64,
    nanoseconds: RangedI32<{ _ }, { _ }>,
    padding: Padding,
}

A span of time with nanosecond precision.

Each Duration is composed of a whole number of seconds and a fractional part represented in nanoseconds.

This implementation allows for negative durations, unlike core::time::Duration.

Fields

seconds: i64

Number of whole seconds.

nanoseconds: RangedI32<{ _ }, { _ }>

Number of nanoseconds within the second. The sign always matches the seconds field.

padding: Padding

Implementations

impl Duration

pub const ZERO: Self = _

Equivalent to 0.seconds().

assert_eq!(Duration::ZERO, 0.seconds());

pub const NANOSECOND: Self = _

Equivalent to 1.nanoseconds().

assert_eq!(Duration::NANOSECOND, 1.nanoseconds());

pub const MICROSECOND: Self = _

Equivalent to 1.microseconds().

assert_eq!(Duration::MICROSECOND, 1.microseconds());

pub const MILLISECOND: Self = _

Equivalent to 1.milliseconds().

assert_eq!(Duration::MILLISECOND, 1.milliseconds());

pub const SECOND: Self = _

Equivalent to 1.seconds().

assert_eq!(Duration::SECOND, 1.seconds());

pub const MINUTE: Self = _

Equivalent to 1.minutes().

assert_eq!(Duration::MINUTE, 1.minutes());

pub const HOUR: Self = _

Equivalent to 1.hours().

assert_eq!(Duration::HOUR, 1.hours());

pub const DAY: Self = _

Equivalent to 1.days().

assert_eq!(Duration::DAY, 1.days());

pub const WEEK: Self = _

Equivalent to 1.weeks().

assert_eq!(Duration::WEEK, 1.weeks());

pub const MIN: Self = _

The minimum possible duration. Adding any negative duration to this will cause an overflow.

pub const MAX: Self = _

The maximum possible duration. Adding any positive duration to this will cause an overflow.

pub const fn is_zero(self) -> bool

Check if a duration is exactly zero.

assert!(0.seconds().is_zero());
assert!(!1.nanoseconds().is_zero());

pub const fn is_negative(self) -> bool

Check if a duration is negative.

assert!((-1).seconds().is_negative());
assert!(!0.seconds().is_negative());
assert!(!1.seconds().is_negative());

pub const fn is_positive(self) -> bool

Check if a duration is positive.

assert!(1.seconds().is_positive());
assert!(!0.seconds().is_positive());
assert!(!(-1).seconds().is_positive());

pub const fn abs(self) -> Self

Get the absolute value of the duration.

This method saturates the returned value if it would otherwise overflow.

assert_eq!(1.seconds().abs(), 1.seconds());
assert_eq!(0.seconds().abs(), 0.seconds());
assert_eq!((-1).seconds().abs(), 1.seconds());

pub const fn unsigned_abs(self) -> StdDuration

Convert the existing Duration to a std::time::Duration and its sign. This returns a std::time::Duration and does not saturate the returned value (unlike Duration::abs).

assert_eq!(1.seconds().unsigned_abs(), 1.std_seconds());
assert_eq!(0.seconds().unsigned_abs(), 0.std_seconds());
assert_eq!((-1).seconds().unsigned_abs(), 1.std_seconds());

pub(crate) const unsafe fn new_unchecked(seconds: i64, nanoseconds: i32) -> Self

Create a new Duration without checking the validity of the components.

Safety

• nanoseconds must be in the range -999_999_999..=999_999_999.

While the sign of nanoseconds is required to be the same as the sign of seconds, this is not a safety invariant.

pub(crate) const fn new_ranged_unchecked( seconds: i64, nanoseconds: RangedI32<{ _ }, { _ }>, ) -> Self

Create a new Duration without checking the validity of the components.

pub const fn new(seconds: i64, nanoseconds: i32) -> Self

Create a new Duration with the provided seconds and nanoseconds. If nanoseconds is at least ±10⁹, it will wrap to the number of seconds.

assert_eq!(Duration::new(1, 0), 1.seconds());
assert_eq!(Duration::new(-1, 0), (-1).seconds());
assert_eq!(Duration::new(1, 2_000_000_000), 3.seconds());

Panics

This may panic if an overflow occurs.

pub(crate) const fn new_ranged( seconds: i64, nanoseconds: RangedI32<{ _ }, { _ }>, ) -> Self

Create a new Duration with the provided seconds and nanoseconds.
