Function malachite_base::vecs::vec_delete_left

pub fn vec_delete_left<T: Copy>(xs: &mut Vec<T>, delete_size: usize)

Deletes several values from the left (beginning) of a Vec.

Using this function is more efficient than deleting the values one by one.

Worst-case complexity

$T(n) = O(\operatorname{max}(1, n - m))$

$M(n) = O(1)$

where $T$ is time, $M$ is additional memory, $n$ = xs.len() before the function is called, and $m$ = delete_size.

Panics

Panics if delete_size is greater than xs.len().

Examples

use malachite_base::vecs::vec_delete_left;

let mut xs = vec![1, 2, 3, 4, 5];
vec_delete_left::<u32>(&mut xs, 3);
assert_eq!(xs, [4, 5]);
