assert!(Duration::from_nanos(0).is_zero());
assert!(Duration::from_secs(0).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, 730023852);
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(5432);
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);
1.3.0 · source

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

1.38.0 · source

pub 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);
1.38.0 · source

pub 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);
