Function cosmic::cosmic_theme::palette::cast::try_from_component_slice_mut

pub fn try_from_component_slice_mut<T>(
    values: &mut [<<T as ArrayCast>::Array as ArrayExt>::Item],
) -> Result<&mut [T], SliceCastError>
where
    T: ArrayCast,

Cast from a mutable slice of color components to a slice of colors.

Errors

The cast will return an error if the length of the input slice is not a multiple of the color’s array length.

Examples

use palette::{cast, Srgb};

let components = &mut [64, 139, 10, 93, 18, 214];
assert_eq!(
    cast::try_from_component_slice_mut::<Srgb<u8>>(components),
    Ok([Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)].as_mut())
)

This produces an error:

use palette::{cast, Srgb};

let components = &mut [64, 139, 10, 93, 18]; // Not a multiple of 3
assert!(cast::try_from_component_slice_mut::<Srgb<u8>>(components).is_err());
