Expand description
Create Duration
s from numeric literals.
Examples
Basic construction of Duration
s.
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));
RunSigned 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));
RunJust 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());
RunWhen 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.
