Struct Duration

1.3.0 · source
pub struct Duration { /* private fields */ }
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.

Durations implement many common traits, including Add, Sub, and other ops traits. It implements Default by returning a zero-length Duration.

§Examples

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);

§Formatting 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 “µs” 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.

1.53.0 · source

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 or two instances of SystemTime. This constraint gives it a value of about 584,942,417,355 years in practice, which is currently used on all platforms.

§Examples

assert_eq!(Duration::MAX, Duration::new(u64::MAX, 1_000_000_000 - 1));
1.3.0 (const: 1.58.0) · source

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.

§Panics

This constructor will panic if the carry from the nanoseconds overflows the seconds counter.

§Examples
use std::time::Duration;

let five_seconds = Duration::new(5, 0);
1.3.0 (const: 1.32.0) · source

pub const fn from_secs(secs: u64) -> Duration

1.27.0 (const: 1.32.0) · source

pub const fn from_nanos(nanos: u64) -> Duration

Creates a new Duration from the specified number of nanoseconds.

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.

§Examples
use std::time::Duration;

let duration = Duration::from_nanos(1_000_000_123);

assert_eq!(1, duration.as_secs());
assert_eq!(123, duration.subsec_nanos());
