Expand description

Create Durations from numeric literals.

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));
Run

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));
Run

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());
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.
