Function group_slice_elements 

pub fn group_slice_elements<T, const N: usize>(source: &[T]) -> &[[T; N]]

Transmutes a slice of n elements into a slice of n / N elements, each of which is an array of N elements.

This function just re-interprets the underlying memory and is thus zero-copy.

Panics

Panics if n is not divisible by N.
