Trait Implementations

impl Clone for DurationUnit

fn clone(&self) -> DurationUnit

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DurationUnit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DurationUnit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl LinearScaledUnit for DurationUnit

const REF_UNIT: Self = Self::Day

Unit used as reference for scaling the units.

fn scale(&self) -> AmountT

Returns factor so that factor * Self::REFUNIT == 1 * self.

fn from_scale(amnt: f64) -> Option<Self>

Returns Some(unit) where unit.scale() == Some(amnt), or None if there is no such unit.

fn is_ref_unit(&self) -> bool

Returns true if self is the reference unit of its unit type.

fn ratio(&self, other: &Self) -> f64

Returns factor so that factor * other == 1 * self.

impl Mul<DurationUnit> for AmountT

type Output = Duration

The resulting type after applying the * operator.

fn mul(self, rhs: DurationUnit) -> Self::Output

Performs the * operation.

impl Mul<f64> for DurationUnit

type Output = Duration

The resulting type after applying the * operator.

fn mul(self, rhs: AmountT) -> Self::Output

Performs the * operation.

impl PartialEq<DurationUnit> for DurationUnit

fn eq(&self, other: &DurationUnit) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Unit for DurationUnit

type QuantityType = Duration

Associated type of quantity

fn iter<'a>() -> Iter<'a, Self>

Returns an iterator over the variants of Self.

fn name(&self) -> &'static str

Returns the name of self.

fn symbol(&self) -> &'static str

Returns the symbol used to represent self.

fn si_prefix(&self) -> Option<SIPrefix>

Returns the SI prefix of self, or None is self is not a SI unit.

fn from_symbol(symbol: &str) -> Option<Self>

Returns Some(unit) where unit.symbol() == symbol, or None if there is no such unit.

fn as_qty(&self) -> Self::QuantityType

Returns 1 * self

fn fmt(&self, form: &mut Formatter<'_>) -> Result<(), Error>

Formats self using the given formatter.
