cu29_units::si::length

Struct meter

pub struct meter;

Expand description

The meter is the SI unit of length. It is defined by taking the fixed numerical value of the speed of light in vacuum c to be 299 792 458 when expressed in the unit m s⁻¹, where the second is defined in terms of the caesium frequency ∆ν_Cs.

Trait Implementations§

impl Clone for meter

fn clone(&self) -> meter

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

impl Conversion<f32> for meter

type T = f32

Conversion factor type specific to the underlying storage type.

fn coefficient() -> <meter 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) -> <meter 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::T
where Self: Sized,

Instance conversion factor. Read more

impl Conversion<f64> for meter

type T = f64

Conversion factor type specific to the underlying storage type.

fn coefficient() -> <meter as Conversion<f64>>::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) -> <meter as Conversion<f64>>::T

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

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> Downcast for T
where T: Any,

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>

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)

Converts &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
