Trait palette::cast::ArraysAsMut

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

Trait for casting a mutable reference to collection of arrays into a mutable 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::ArraysAsMut, Srgb};

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

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

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

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

Required Methods

fn arrays_as_mut(&mut self) -> &mut C

Cast this collection of arrays into a mutable collection of colors.
