Struct candela
pub struct candela;Expand description
The candela is the SI unit of luminous intensity in a given direction. It is defined by taking the fixed numerical value of the luminous efficacy of monochromatic radiation of frequency 540 × 10¹² Hz, Kcd, to be 683 when expressed in the unit lm W⁻¹, which is equal to cd sr W⁻¹, or cd sr kg⁻¹ m⁻² s³, where the kilogram, meter, and second are defined in terms of h, c and ∆νCs.
Trait Implementations§
§impl Conversion<f32> for candela
impl Conversion<f32> for candela
§fn coefficient() -> <candela as Conversion<f32>>::T
fn coefficient() -> <candela as Conversion<f32>>::T
Coefficient portion of conversion factor for
converting the given unit. To convert to the base unit for the quantity use
(value + constant()) * coefficient(). To convert from the base unit, (value / coefficient()) - constant() is used. Implementation should return the multiplicative identity
(Self::T::one()) if no coefficient exists.§fn constant(op: ConstantOp) -> <candela as Conversion<f32>>::T
fn constant(op: ConstantOp) -> <candela as Conversion<f32>>::T
Constant portion of conversion factor for
converting the given unit. To convert to the base unit for the quantity use
(value + constant()) * coefficient(). To convert from the base unit, (value / coefficient()) - constant() is used. Implementation should return the additive identity (Self::T::zero())
if no constant exists. See [ConstantOp] documentation for details about parameter use to
ensure the method optimizes correctly.§fn conversion(&self) -> Self::Twhere

fn into_any(self: Box<T>) -> Box<dyn Any>
Converts
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be
downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
Converts
Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further
downcast into Rc<ConcreteType> where ConcreteType implements Trait.§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Converts
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Converts
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.
