Struct Duration

#[non_exhaustive]
pub struct Duration(pub Duration);

Tuple Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

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_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);
