}
Expand description
Trait for casting a collection of color components into a 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::ComponentsFrom, Srgb};
let array: [_; 2] = [Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)];
let slice: &[_] = &[Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)];
let slice_mut: &mut [_] = &mut [Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)];
let vec: Vec<_> = vec![Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)];
assert_eq!(<[_; 6]>::components_from(array), [64, 139, 10, 93, 18, 214]);
assert_eq!(<&[_]>::components_from(slice), [64, 139, 10, 93, 18, 214]);
assert_eq!(<&mut [_]>::components_from(slice_mut), [64, 139, 10, 93, 18, 214]);
assert_eq!(Vec::<_>::components_from(vec), vec![64, 139, 10, 93, 18, 214]);
Owning types can be cast as slices, too:
use palette::{cast::ComponentsFrom, Srgb};
let array: [_; 2] = [Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)];
let mut vec: Vec<_> = vec![Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)];
assert_eq!(<&[_]>::components_from(&array), [64, 139, 10, 93, 18, 214]);
assert_eq!(<&mut [_]>::components_from(&mut vec), [64, 139, 10, 93, 18, 214]);
Required Methods§
sourcefn components_from(colors: C) -> Self
fn components_from(colors: C) -> Self
