Methods from Deref<Target = Duration>

pub const SECOND: Duration

pub const MILLISECOND: Duration

pub const MICROSECOND: Duration

pub const NANOSECOND: Duration

pub const ZERO: Duration

pub const MAX: Duration

pub fn is_zero(&self) -> bool

Returns true if this Duration spans no time.

Examples

use std::time::Duration;

assert!(Duration::ZERO.is_zero());
assert!(Duration::new(0, 0).is_zero());
assert!(Duration::from_nanos(0).is_zero());
assert!(Duration::from_secs(0).is_zero());

assert!(!Duration::new(1, 1).is_zero());
assert!(!Duration::from_nanos(1).is_zero());
assert!(!Duration::from_secs(1).is_zero());

pub fn as_secs(&self) -> u64

Returns the number of whole seconds contained by this Duration.

The returned value does not include the fractional (nanosecond) part of the duration, which can be obtained using subsec_nanos.

Examples

use std::time::Duration;

let duration = Duration::new(5, 730_023_852);
assert_eq!(duration.as_secs(), 5);

To determine the total number of seconds represented by the Duration including the fractional part, use as_secs_f64 or as_secs_f32

pub fn subsec_millis(&self) -> u32

Returns the fractional part of this Duration, in whole milliseconds.

This method does not return the length of the duration when represented by milliseconds. The returned number always represents a fractional portion of a second (i.e., it is less than one thousand).

Examples

use std::time::Duration;

let duration = Duration::from_millis(5_432);
assert_eq!(duration.as_secs(), 5);
assert_eq!(duration.subsec_millis(), 432);

pub fn subsec_micros(&self) -> u32

Returns the fractional part of this Duration, in whole microseconds.

This method does not return the length of the duration when represented by microseconds. The returned number always represents a fractional portion of a second (i.e., it is less than one million).

Examples

use std::time::Duration;

let duration = Duration::from_micros(1_234_567);
assert_eq!(duration.as_secs(), 1);
assert_eq!(duration.subsec_micros(), 234_567);

pub fn subsec_nanos(&self) -> u32

Returns the fractional part of this Duration, in nanoseconds.

This method does not return the length of the duration when represented by nanoseconds. The returned number always represents a fractional portion of a second (i.e., it is less than one billion).

Examples

use std::time::Duration;

let duration = Duration::from_millis(5_010);
assert_eq!(duration.as_secs(), 5);
assert_eq!(duration.subsec_nanos(), 10_000_000);

pub fn as_millis(&self) -> u128

Returns the total number of whole milliseconds contained by this Duration.

Examples

use std::time::Duration;

let duration = Duration::new(5, 730_023_852);
assert_eq!(duration.as_millis(), 5_730);

pub fn as_micros(&self) -> u128

Returns the total number of whole microseconds contained by this Duration.

Examples

use std::time::Duration;

let duration = Duration::new(5, 730_023_852);
assert_eq!(duration.as_micros(), 5_730_023);

pub fn as_nanos(&self) -> u128

Returns the total number of nanoseconds contained by this Duration.

Examples

use std::time::Duration;

let duration = Duration::new(5, 730_023_852);
assert_eq!(duration.as_nanos(), 5_730_023_852);

pub fn as_secs_f64(&self) -> f64

Returns the number of seconds contained by this Duration as f64.

The returned value includes the fractional (nanosecond) part of the duration.

Examples

use std::time::Duration;

let dur = Duration::new(2, 700_000_000);
assert_eq!(dur.as_secs_f64(), 2.7);

pub fn as_secs_f32(&self) -> f32

Returns the number of seconds contained by this Duration as f32.

The returned value includes the fractional (nanosecond) part of the duration.

Examples

use std::time::Duration;

let dur = Duration::new(2, 700_000_000);
assert_eq!(dur.as_secs_f32(), 2.7);

pub fn as_millis_f64(&self) -> f64

🔬This is a nightly-only experimental API. (duration_millis_float)

Returns the number of milliseconds contained by this Duration as f64.

The returned value includes the fractional (nanosecond) part of the duration.

Examples

#![feature(duration_millis_float)]
use std::time::Duration;

let dur = Duration::new(2, 345_678_000);
assert_eq!(dur.as_millis_f64(), 2_345.678);

pub fn as_millis_f32(&self) -> f32

🔬This is a nightly-only experimental API. (duration_millis_float)

Returns the number of milliseconds contained by this Duration as f32.

The returned value includes the fractional (nanosecond) part of the duration.

Examples

#![feature(duration_millis_float)]
use std::time::Duration;

let dur = Duration::new(2, 345_678_000);
assert_eq!(dur.as_millis_f32(), 2_345.678);

Trait Implementations
