Struct humantime::Duration

pub struct Duration(_);

A wrapper for duration that has FromStr implementation

This is useful if you want to use it somewhere where FromStr is expected.

See parse_duration for the description of the format.

Example

use std::time::Duration;
let x: Duration;
x = "12h 5min 2ns".parse::<humantime::Duration>().unwrap().into();
assert_eq!(x, Duration::new(12*3600 + 5*60, 2))

Methods from Deref<Target = StdDuration>

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 const fn is_zero(&self) -> bool

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

Returns true if this Duration spans no time.

Examples

#![feature(duration_zero)]
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 const 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, 730023852);
assert_eq!(duration.as_secs(), 5);

To determine the total number of seconds represented by the Duration, use as_secs in combination with subsec_nanos:

use std::time::Duration;

let duration = Duration::new(5, 730023852);

assert_eq!(5.730023852,
           duration.as_secs() as f64
           + duration.subsec_nanos() as f64 * 1e-9);

pub const 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(5432);
assert_eq!(duration.as_secs(), 5);
assert_eq!(duration.subsec_millis(), 432);

pub const 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 const 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(5010);
assert_eq!(duration.as_secs(), 5);
assert_eq!(duration.subsec_nanos(), 10_000_000);

pub const 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, 730023852);
assert_eq!(duration.as_millis(), 5730);

pub const 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, 730023852);
assert_eq!(duration.as_micros(), 5730023);

pub const 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, 730023852);
assert_eq!(duration.as_nanos(), 5730023852);

pub const fn as_secs_f64(&self) -> f64

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

The returned value does include 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 const fn as_secs_f32(&self) -> f32

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

The returned value does include 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);
