Trait AsComponents

pub trait AsComponents<C>
where
    C: ?Sized,
{
    // Required method
    fn as_components(&self) -> &C;
}

Trait for casting a reference to a collection of colors into a reference to a collection of color components without copying.

This trait is meant as a more convenient alternative to the free functions in cast, to allow method chaining among other things.

Examples

use palette::{cast::AsComponents, Srgb};

let array: [_; 2] = [Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)];
let slice: &[_] = &[Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)];
let vec: Vec<_> = vec![Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)];

assert_eq!(array.as_components(), &[64, 139, 10, 93, 18, 214]);
assert_eq!(slice.as_components(), &[64, 139, 10, 93, 18, 214]);
assert_eq!(vec.as_components(), &[64, 139, 10, 93, 18, 214]);

Required Methods

fn as_components(&self) -> &C

Cast this collection of colors into a collection of color components.
