Struct uom::si::luminous_intensity::candela

pub struct candela;

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, K_cd, 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 ∆ν_Cs.

Trait Implementations

impl Clone for candela

fn clone(&self) -> candela

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Conversion<u16> for candela

type T = Ratio<u16>

Conversion factor type specific to the underlying storage type.

fn coefficient() -> Self::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) -> Self::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::T

where Self: Sized,

Instance conversion factor.

impl Conversion<u32> for candela

type T = Ratio<u32>

Conversion factor type specific to the underlying storage type.

fn coefficient() -> Self::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) -> Self::T

Constant portion of conversion factor for converting the given unit. To convert to the base unit for the quantity use (value + constant()) * coefficient().
