Trait palette::cast::ArraysAs

pub trait ArraysAs<C: ?Sized> {
    // Required method
    fn arrays_as(&self) -> &C;
}

Trait for casting a reference to collection of arrays into a reference to collection of colors 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::ArraysAs, Srgb};

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

let colors: &[Srgb<u8>] = array.arrays_as();
assert_eq!(colors, &[Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)]);

let colors: &[Srgb<u8>] = slice.arrays_as();
assert_eq!(colors, &[Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)]);

let colors: &[Srgb<u8>] = vec.arrays_as();
assert_eq!(colors, &[Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)]);

Required Methods

fn arrays_as(&self) -> &C

Cast this collection of arrays into a collection of colors.
