Function array_append::push_left

pub fn push_left<const N: usize, T>(a: [T; N], b: T) -> [T; 1 + N]

Extends the given element b by the given array a. Returns a new array which is the direct extension of a by b. No elements are dropped, copied or cloned.

Example

let arr = [2usize, 3, 4, 5];
let elem = 1;
let prepended = push_left(arr, elem);

assert_eq!(prepended, [1, 2, 3, 4, 5]);
