pub struct Duration {
secs: u64,
nanos: Nanoseconds,
}
Expand description
A Duration
type to represent a span of time, typically used for system
timeouts.
Each Duration
is composed of a whole number of seconds and a fractional part
represented in nanoseconds. If the underlying system does not support
nanosecond-level precision, APIs binding a system timeout will typically round up
the number of nanoseconds.
Duration
s implement many common traits, including Add
, Sub
, and other
ops
traits. It implements Default
by returning a zero-length Duration
.
ยงExamples
use std::time::Duration;
let five_seconds = Duration::new(5, 0);
let five_seconds_and_five_nanos = five_seconds + Duration::new(0, 5);
assert_eq!(five_seconds_and_five_nanos.as_secs(), 5);
assert_eq!(five_seconds_and_five_nanos.subsec_nanos(), 5);
let ten_millis = Duration::from_millis(10);
ยงFormatting Duration
values
Duration
intentionally does not have a Display
impl, as there are a
variety of ways to format spans of time for human readability. Duration
provides a Debug
impl that shows the full precision of the value.
The Debug
output uses the non-ASCII โยตsโ suffix for microseconds. If your
program output may appear in contexts that cannot rely on full Unicode
compatibility, you may wish to format Duration
objects yourself or use a
crate to do so.

pub const ZERO: Duration
A duration of zero time.
ยงExamples

pub const MAX: Duration
The maximum duration.
May vary by platform as necessary. Must be able to contain the difference between
two instances of Instant

which is currently used on all platforms.
ยงExamples
use std::time::Duration;
assert_eq!(Duration::MAX, Duration::new(u64::MAX, 1_000_000_000 - 1));
1.3.0 (const: 1.58.0) ยท Sourcepub const fn new(secs: u64, nanos: u32) -> Duration
pub const fn new(secs: u64, nanos: u32) -> Duration
Creates a new Duration
from the specified number of whole seconds and
additional nanoseconds.
If the number of nanoseconds is greater than 1 billion (the number of nanoseconds in a second), then it will carry over into the seconds provided.
ยงPanics
This constructor will panic if the carry from the nanoseconds overflows the seconds counter.
ยงExamples

Note: Using this on the return value of as_nanos()
might cause unexpected behavior:
as_nanos()
returns a u128, and can return values that do not fit in u64, e.g. 585 years.
Instead, consider using the pattern Duration::new(d.as_secs(), d.subsec_nanos())
if you cannot copy/clone the Duration directly.
ยงExamples
use std::time::Duration;
let duration = Duration::from_nanos(1_000_000_123);
