Function array_chunks_mut

Source 
pub fn array_chunks_mut<T, const N: usize>(
    vals: &mut [T],
) -> ArrayChunksMut<'_, T, N> ⓘ
Expand description

Returns an iterator over N elements of the slice at a time, starting at the beginning of the slice.

The chunks are mutable array references and do not overlap. If N does not divide the length of the slice, then the last up to N-1 elements will be omitted and can be retrieved from the into_remainder function of the iterator.

This method is the const generic equivalent of chunks_exact_mut.

§Panics

Panics if N is 0. This check will most probably get changed to a compile time error before this method gets stabilized.

§Examples

let v = &mut [0, 0, 0, 0, 0];
let mut count = 1;

for chunk in array_util::array_chunks_mut(v) {
    *chunk = [count; 2];
    count += 1;
}
assert_eq!(v, &[1, 1, 2, 2, 0]);
