Function from_component_vec

pub fn from_component_vec<T>(
    values: Vec<<T::Array as ArrayExt>::Item>,
) -> Vec<T>
where
    T: ArrayCast,

The same as try_from_component_vec but panics on error.

Panics

The cast will panic if the length or capacity of the input Vec is not a multiple of the color’s array length.

Examples

use palette::{cast, Srgb};

let components = vec![64, 139, 10, 93, 18, 214];
assert_eq!(
    cast::from_component_vec::<Srgb<u8>>(components),
    vec![Srgb::new(64u8, 139, 10), Srgb::new(93, 18, 214)]
)

This panics due to the incorrect length:

use palette::{cast, Srgb};

// Not a multiple of 3:
let components = vec![64, 139, 10, 93, 18, 214, 0, 123];
cast::from_component_vec::<Srgb<u8>>(components);

This panics due to the incorrect capacity:

use palette::{cast, Srgb};

let mut components = vec![64, 139, 10, 93, 18, 214];
components.reserve_exact(2); // Not a multiple of 3
cast::from_component_vec::<Srgb<u8>>(components);
