[−][src]Trait time::NumericalStdDurationShort

pub trait NumericalStdDurationShort {
    fn nanoseconds(self) -> StdDuration;

    fn microseconds(self) -> StdDuration;

    fn milliseconds(self) -> StdDuration;

    fn seconds(self) -> StdDuration;

    fn minutes(self) -> StdDuration;

    fn hours(self) -> StdDuration;

    fn days(self) -> StdDuration;

    fn weeks(self) -> StdDuration;
}

Create std::time::Durations from primitive and core numeric types. Unless you are always expecting a std::time::Duration, you should prefer to use NumericalStdDuration for clarity.

Due to limitations in rustc, these methods are currently not const fn. See this RFC for details.

Examples

Basic construction of std::time::Durations.

assert_eq!(5.nanoseconds(), Duration::from_nanos(5));
assert_eq!(5.microseconds(), Duration::from_micros(5));
assert_eq!(5.milliseconds(), Duration::from_millis(5));
assert_eq!(5.seconds(), Duration::from_secs(5));
assert_eq!(5.minutes(), Duration::from_secs(5 * 60));
assert_eq!(5.hours(), Duration::from_secs(5 * 3_600));
assert_eq!(5.days(), Duration::from_secs(5 * 86_400));
assert_eq!(5.weeks(), Duration::from_secs(5 * 604_800));

Just like any other std::time::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.

Required methods

fn nanoseconds(self) -> StdDuration

Create a std::time::Duration from the number of nanoseconds.

fn microseconds(self) -> StdDuration

Create a std::time::Duration from the number of microseconds.

fn milliseconds(self) -> StdDuration

Create a std::time::Duration from the number of milliseconds.

fn seconds(self) -> StdDuration

Create a std::time::Duration from the number of seconds.

fn minutes(self) -> StdDuration

Create a std::time::Duration from the number of minutes.

fn hours(self) -> StdDuration

Create a std::time::Duration from the number of hours.

fn days(self) -> StdDuration

Create a std::time::Duration from the number of days.

fn weeks(self) -> StdDuration

Create a std::time::Duration from the number of weeks.

Implementations on Foreign Types

impl NumericalStdDurationShort for u8[src]

impl NumericalStdDurationShort for u16[src]

impl NumericalStdDurationShort for u32[src]

impl NumericalStdDurationShort for u64[src]

impl NumericalStdDurationShort for NonZeroU8[src]

impl NumericalStdDurationShort for NonZeroU16[src]

impl NumericalStdDurationShort for NonZeroU32[src]

impl NumericalStdDurationShort for NonZeroU64[src]

impl NumericalStdDurationShort for i32[src]

Implement on i32 because that's the default type for integers. This performs a runtime check and panics if the value is negative.

impl NumericalStdDurationShort for f64[src]

Implement on f64 because that's the default type for floats. This performs a runtime check and panics if the value is negative.
