Get simultaneous mutable access to multiple elements of a mutable array, slice or Vec. This is a generalization of [slice::split_at_mut] to individual elements rather than just a pair of subslices.

use mut_elems::*;

let mut a = [1u8, 2, 3, 4];

let es: [&mut u8; 2] = a.mut_elems(&[1, 3]).unwrap();
*es[0] = 5;
*es[1] = 7;
assert_eq!([1, 5, 3, 7], a);

let es: [&mut u8; 4] = a.as_mut_elems();
*es[1] = 5;
*es[3] = 7;
assert_eq!([1, 5, 3, 7], a);

let mut aref: &mut [u8] = a.as_mut();
let mut es: Vec<&mut u8> = aref.as_mut_elems_vec();
*es[1] = 5;
*es[3] = 7;
assert_eq!([1, 5, 3, 7], a);
