Trait FromUints

pub trait FromUints<U> {
    // Required method
    fn from_uints(uints: U) -> Self;
}

Trait for casting a collection of colors from a collection of unsigned integers 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::FromUints, rgb::PackedArgb, Srgba};

let array: [_; 2] = [0xFF17C64C, 0xFF5D12D6];
let slice: &[_] = &[0xFF17C64C, 0xFF5D12D6];
let slice_mut: &mut [_] = &mut [0xFF17C64C, 0xFF5D12D6];
let vec: Vec<_> = vec![0xFF17C64C, 0xFF5D12D6];

assert_eq!(
    <[PackedArgb; 2]>::from_uints(array),
    [
        Srgba::new(0x17, 0xC6, 0x4C, 0xFF).into(),
        Srgba::new(0x5D, 0x12, 0xD6, 0xFF).into()
    ]
);

assert_eq!(
    <&[PackedArgb]>::from_uints(slice),
    [
        Srgba::new(0x17, 0xC6, 0x4C, 0xFF).into(),
        Srgba::new(0x5D, 0x12, 0xD6, 0xFF).into()
    ]
);

assert_eq!(
    <&mut [PackedArgb]>::from_uints(slice_mut),
    [
        Srgba::new(0x17, 0xC6, 0x4C, 0xFF).into(),
        Srgba::new(0x5D, 0x12, 0xD6, 0xFF).into()
    ]
);

assert_eq!(
    Vec::<PackedArgb>::from_uints(vec),
    vec![
        Srgba::new(0x17, 0xC6, 0x4C, 0xFF).into(),
        Srgba::new(0x5D, 0x12, 0xD6, 0xFF).into()
    ]
);

Owning types can be cast as slices, too:

use palette::{cast::FromUints, rgb::PackedArgb, Srgba};

let array: [_; 2] = [0xFF17C64C, 0xFF5D12D6];
let mut vec: Vec<_> = vec![0xFF17C64C, 0xFF5D12D6];

assert_eq!(
    <&[PackedArgb]>::from_uints(&array),
    [
        Srgba::new(0x17, 0xC6, 0x4C, 0xFF).into(),
        Srgba::new(0x5D, 0x12, 0xD6, 0xFF).into()
    ]
);

assert_eq!(
    <&mut [PackedArgb]>::from_uints(&mut vec),
    [
        Srgba::new(0x17, 0xC6, 0x4C, 0xFF).into(),
        Srgba::new(0x5D, 0x12, 0xD6, 0xFF).into()
    ]
);
