Trait ColorComponent

pub trait ColorComponent: Copy {
    const ZERO: Self;
    const HALF: Self;
    const MAX: Self;

    // Required methods
    fn as_f32(self) -> f32;
    fn from_f32(value: f32) -> Self;

    // Provided methods
    fn convert<U>(self) -> U
       where U: ColorComponent { ... }
    fn lerp(start: Self, end: Self, t: f32) -> Self { ... }
}

A trait representing a color component in a color.

Required Associated Constants

const ZERO: Self

Min value (black)

const HALF: Self

Half value (gray)

const MAX: Self

Max value (white)

Required Methods

fn as_f32(self) -> f32

Convert into an f32

fn from_f32(value: f32) -> Self

Convert from an f32

Provided Methods

fn convert<U>(self) -> U

where U: ColorComponent,

Convert from one type to another

fn lerp(start: Self, end: Self, t: f32) -> Self

Linearly interpolate between start and end values.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
