Function superimpose

pub fn superimpose<T, const MAIN_SIZE: usize, const SUB_SIZE: usize>(
    main_array: [T; MAIN_SIZE],
    sub_array: [T; SUB_SIZE],
    starting_from: usize,
) -> [T; MAIN_SIZE]
where
    T: Copy,

Superimpose an sized sub_array upon another main_array at index starting_from.

Create a copy of the main_array and insert all elements of sub_array into it, starting from the starting_from index. If the sub_array has more elements than fit in the main_array they are ignored.

Examples

use array_utils::superimpose;

assert_eq!(
    superimpose([0; 8], [1, 3, 3, 7], 2),
    [0, 0, 1, 3, 3, 7, 0, 0]
);

// Elements that don't fit in the main array size are ignored.
assert_eq!(
    superimpose([1, 2, 3], [4, 2], 2),
    [1, 2, 4]
);
