[][src]Struct euclid::TypedScale

#[repr(C)]
pub struct TypedScale<T, Src, Dst>(pub T, _);

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;
