Function join 

pub fn join<T, const LEFT_SIZE: usize, const RIGHT_SIZE: usize, const RESULT_SIZE: usize>(
    left: [T; LEFT_SIZE],
    right: [T; RIGHT_SIZE],
    fill: T,
) -> [T; RESULT_SIZE]
where
    T: Copy,

Join two sized arrays together into a new array.

Create a sized array which contain all the elements of left and right back to back. If there are any elements left to fill, they are filled up with the fill value. Any values of left or right that don’t fit in the given buffer are ignored.

Examples

use array_utils::join;

assert_eq!(join([1, 2, 3], [4, 5, 6], 0), [1, 2, 3, 4, 5, 6]);

// Leftover elements are filled up
assert_eq!(join([1, 2, 3], [4, 5, 6], 0), [1, 2, 3, 4, 5, 6, 0, 0]);

// The input arrays are truncated if the resulting array is too short.
assert_eq!(join([1, 2, 3], [4, 5, 6], 0), [1, 2, 3, 4, 5]);
