Expand description
Create std::time::Duration
s from numeric literals.
§Examples
Basic construction of std::time::Duration
s.
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.
