Struct euclid::TypedScale
source · #[repr(C)]pub struct TypedScale<T, Src, Dst>(pub T, _);
Expand description
A scaling factor between two different units of measurement.
This is effectively a type-safe float, intended to be used in combination with other types like
length::Length
to enforce conversion between systems of measurement at compile time.
Src
and Dst
represent the units before and after multiplying a value by a TypedScale
. They
may be types without values, such as empty enums. For example:
use euclid::TypedScale;
use euclid::Length;
enum Mm {};
enum Inch {};
let mm_per_inch: TypedScale<f32, Inch, Mm> = TypedScale::new(25.4);
let one_foot: Length<f32, Inch> = Length::new(12.0);
let one_foot_in_mm: Length<f32, Mm> = one_foot * mm_per_inch;
