Expand description
Trait for casting a collection of arrays from 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::ArraysFrom, 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!(<[_; 2]>::arrays_from(array), [[64, 139, 10], [93, 18, 214]]);
assert_eq!(<&[_]>::arrays_from(slice), [[64, 139, 10], [93, 18, 214]]);
assert_eq!(<&mut [_]>::arrays_from(slice_mut), [[64, 139, 10], [93, 18, 214]]);
assert_eq!(Vec::<_>::arrays_from(vec), vec![[64, 139, 10], [93, 18, 214]]);
Owning types can be cast as slices, too:
use palette::{cast::ArraysFrom, 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!(<&[_]>::arrays_from(&array), [[64, 139, 10], [93, 18, 214]]);
assert_eq!(<&mut [_]>::arrays_from(&mut vec), [[64, 139, 10], [93, 18, 214]]);
Required Methods§
sourcefn arrays_from(colors: C) -> Self
fn arrays_from(colors: C) -> Self
Cast a collection of colors into a collection of arrays.
Object Safety§
This trait is not object safe.
