T: ArrayCast,
Expand description
Cast from an array of colors to an array of color components.
§Panics
It’s unfortunately not able to infer the length of the component array,
until generic const expressions are stabilized. In the meantime, it’s going
to panic if M
isn’t N * T::Array::LENGTH
. A future version will remove
the M
parameter and make the mismatch a compiler error.
No try_*
alternative is provided, since the array size can’t be changed
during runtime.
§Examples
use palette::{cast, Srgb};
let colors = [Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)];
assert_eq!(cast::into_component_array(colors), [64, 139, 10, 93, 18, 214])
It panics when the array lengths don’t match up:
ⓘ
use palette::{cast, Srgb};
let colors = [Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)];
assert_eq!(cast::into_component_array(colors), [64, 139, 10]) // Too short
