Expand description

Cast from an array reference to a color type reference.

use palette::{cast, Srgb};

let array = [23, 198, 76];
assert_eq!(cast::from_array_ref::<Srgb<u8>>(&array),  &Srgb::new(23, 198, 76));

It’s also possible to use From, Into and AsRef when casting built-in types:

use palette::Srgb;

let array = [23, 198, 76];

// Arrays implement `AsRef`:
let color1: &Srgb<u8> = array.as_ref();

// Array references implement `Into`:
let color2: &Srgb<u8> = (&array).into();

// Color references implement `From`:
let color3 = <&Srgb<u8>>::from(&array);
