pub struct Duration { /* private fields */ }
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
.

impl Duration
sourcepub const NANOSECOND: Self = _
pub const NANOSECOND: Self = _
sourcepub const MICROSECOND: Self = _
pub const MICROSECOND: Self = _
sourcepub const MILLISECOND: Self = _
pub const MILLISECOND: Self = _
sourcepub const MIN: Self = _
pub const MIN: Self = _
The minimum possible duration. Adding any negative duration to this will cause an overflow.
sourcepub const MAX: Self = _
pub const MAX: Self = _
The maximum possible duration. Adding any positive duration to this will cause an overflow.
sourcepub const fn is_negative(self) -> bool
pub const fn is_negative(self) -> bool
sourcepub const fn is_positive(self) -> bool
pub const fn is_positive(self) -> bool
sourcepub const fn unsigned_abs(self) -> StdDuration
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
).
sourcepub const fn new(seconds: i64, nanoseconds: i32) -> Self
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.
sourcepub const fn weeks(weeks: i64) -> Self
pub const fn weeks(weeks: i64) -> Self
Create a new Duration
with the given number of weeks. Equivalent to
Duration::seconds(weeks * 604_800)
.
§Panics
This may panic if an overflow occurs.
sourcepub const fn days(days: i64) -> Self
pub const fn days(days: i64) -> Self
Create a new Duration
with the given number of days. Equivalent to
Duration::seconds(days * 86_400)
.
§Panics
This may panic if an overflow occurs.
sourcepub const fn hours(hours: i64) -> Self
pub const fn hours(hours: i64) -> Self
Create a new Duration
with the given number of hours. Equivalent to
Duration::seconds(hours * 3_600)
.
§Panics
This may panic if an overflow occurs.
sourcepub const fn minutes(minutes: i64) -> Self
pub const fn minutes(minutes: i64) -> Self
Create a new Duration
with the given number of minutes. Equivalent to
Duration::seconds(minutes * 60)
.
§Panics
This may panic if an overflow occurs.

source§impl Display for Duration
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:
For the purposes of this implementation, a day is exactly 24 hours and a minute is exactly 60 seconds.
