    // Required methods
    fn std_nanoseconds(self) -> StdDuration;
    fn std_microseconds(self) -> StdDuration;
    fn std_milliseconds(self) -> StdDuration;

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));

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()
);

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.
