Struct time::duration::Duration

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

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

Run
source

pub const HOUR: Self = _

Equivalent to 1.hours().

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

pub const DAY: Self = _

Equivalent to 1.days().

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

pub const WEEK: Self = _

Equivalent to 1.weeks().

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

pub const MIN: Self = _

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

source

pub const MAX: Self = _

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

source

pub const fn is_zero(self) -> bool

Check if a duration is exactly zero.

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

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());
Run
source

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());
Run
source

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());
Run
source

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());

source

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.

source

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

source

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());

impl Display for Duration

The format returned by this implementation is not stable and must not be relied upon.

By default this produces an exact, full-precision printout of the duration. For a concise, rounded printout instead, you can use the .N format specifier:

println!("{duration:.3}");
Run

For the purposes of this implementation, a day is exactly 24 hours and a minute is exactly 60 seconds.
