Trait palette::cast::AsArrays

pub trait AsArrays<A: ?Sized> {
    // Required method
    fn as_arrays(&self) -> &A;
}

Trait for casting a reference to a collection of colors into a reference to a collection of arrays 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::AsArrays, 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_arrays(), &[[64, 139, 10], [93, 18, 214]]);
assert_eq!(slice.as_arrays(), &[[64, 139, 10], [93, 18, 214]]);
assert_eq!(vec.as_arrays(), &[[64, 139, 10], [93, 18, 214]]);

Required Methods

fn as_arrays(&self) -> &A

Cast this collection of colors into a collection of arrays.
