Expand description

Create std::time::Durations from numeric literals.

Examples

Basic construction of std::time::Durations.

assert_eq!(5.std_nanoseconds(), Duration::from_nanos(5));
assert_eq!(5.std_microseconds(), Duration::from_micros(5));
assert_eq!(5.std_milliseconds(), Duration::from_millis(5));
assert_eq!(5.std_seconds(), Duration::from_secs(5));
assert_eq!(5.std_minutes(), Duration::from_secs(5 * 60));
assert_eq!(5.std_hours(), Duration::from_secs(5 * 3_600));
assert_eq!(5.std_days(), Duration::from_secs(5 * 86_400));
assert_eq!(5.std_weeks(), Duration::from_secs(5 * 604_800));
Run

Just like any other std::time::Duration, they can be added, subtracted, etc.

assert_eq!(
    2.std_seconds() + 500.std_milliseconds(),
    2_500.std_milliseconds()
);
assert_eq!(
    2.std_seconds() - 500.std_milliseconds(),
    1_500.std_milliseconds()
);
Run

When called on floating point values, any remainder of the floating point value will be truncated. Keep in mind that floating point numbers are inherently imprecise and have limited capacity.
