Trait kvarn::prelude::chrono::NumericalDuration

pub trait NumericalDuration: Sealed {
    // Required methods
    fn nanoseconds(self) -> Duration;
    fn microseconds(self) -> Duration;
    fn milliseconds(self) -> Duration;
    fn seconds(self) -> Duration;

}

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));

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.
