Struct humantime::Duration [] [src]

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>

1.3.0
[src]

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);

1.3.0
[src]

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);

1.16.0
[src]

Checked Duration addition. Computes self + other, returning None if overflow occurred.

Examples

Basic usage:

use std::time::Duration;

assert_eq!(Duration::new(0, 0).checked_add(Duration::new(0, 1)), Some(Duration::new(0, 1)));
assert_eq!(Duration::new(1, 0).checked_add(Duration::new(std::u64::MAX, 0)), None);

1.16.0
[src]

Checked Duration subtraction. Computes self - other, returning None if the result would be negative or if underflow occurred.

Examples

Basic usage:

use std::time::Duration;

assert_eq!(Duration::new(0, 1).checked_sub(Duration::new(0, 0)), Some(Duration::new(0, 1)));
assert_eq!(Duration::new(0, 0).checked_sub(Duration::new(0, 1)), None);

1.16.0
[src]

Checked Duration multiplication. Computes self * other, returning None if overflow occurred.

Examples

Basic usage:

use std::time::Duration;

assert_eq!(Duration::new(0, 500_000_001).checked_mul(2), Some(Duration::new(1, 2)));
assert_eq!(Duration::new(std::u64::MAX - 1, 0).checked_mul(2), None);

1.16.0
[src]

Checked Duration division. Computes self / other, returning None if other == 0.

Examples

Basic usage:

use std::time::Duration;

assert_eq!(Duration::new(2, 0).checked_div(2), Some(Duration::new(1, 0)));
assert_eq!(Duration::new(1, 0).checked_div(2), Some(Duration::new(0, 500_000_000)));
assert_eq!(Duration::new(2, 0).checked_div(0), None);
