Trait time::ext::NumericalDuration [−][src]
Create Durations from primitive and core numeric types.
This trait can be imported with use time::prelude::*.
Due to limitations in rustc, these methods are currently not const fn.
See RFC 2632 for details.
Examples
Basic construction of Durations.
assert_eq!(5.nanoseconds(), Duration::nanoseconds(5)); assert_eq!(5.microseconds(), Duration::microseconds(5)); assert_eq!(5.milliseconds(), Duration::milliseconds(5)); assert_eq!(5.seconds(), Duration::seconds(5)); assert_eq!(5.minutes(), Duration::minutes(5)); assert_eq!(5.hours(), Duration::hours(5)); assert_eq!(5.days(), Duration::days(5)); assert_eq!(5.weeks(), Duration::weeks(5));
Signed integers work as well!
assert_eq!((-5).nanoseconds(), Duration::nanoseconds(-5)); assert_eq!((-5).microseconds(), Duration::microseconds(-5)); assert_eq!((-5).milliseconds(), Duration::milliseconds(-5)); assert_eq!((-5).seconds(), Duration::seconds(-5)); assert_eq!((-5).minutes(), Duration::minutes(-5)); assert_eq!((-5).hours(), Duration::hours(-5)); assert_eq!((-5).days(), Duration::days(-5)); assert_eq!((-5).weeks(), Duration::weeks(-5));
Just like any other Duration, they can be added, subtracted, etc.
assert_eq!(2.seconds() + 500.milliseconds(), 2_500.milliseconds()); assert_eq!(2.seconds() - 500.milliseconds(), 1_500.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.
