pub fn group_slice_elements<T, const N: usize>(source: &[T]) -> &[[T; N]]
Expand description
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
.
§Example
let a = [0_u32, 1, 2, 3, 4, 5, 6, 7];
let b: &[[u32; 2]] = group_slice_elements(&a);
assert_eq!(&[[0, 1], [2, 3], [4, 5], [6, 7]], b);
