Function drop_by_index 

Source 
pub fn drop_by_index<T>(collection: &[T], indexes: &[isize]) -> Vec<T>
where
    T: Clone,
Expand description

Removes elements from a collection at the specified indices. Supports negative indices which count from the end of the collection. Indices that are out of bounds are ignored.

Time Complexity: O(n log n) for sorting the indices, O(m) for cloning, where m is the length of the resulting collection.

§Arguments

  • collection - A slice of items from which elements will be removed.
  • indexes - A slice of indices at which elements should be removed.

§Type Parameters

  • T - The type of elements in the collection. Must implement Clone.

§Returns

  • Vec<T> - A vector containing the elements after removing the specified indices.

§Examples

use lowdash::drop_by_index;

let numbers = vec![1, 2, 3, 4, 5];
let result = drop_by_index(&numbers, &[1, 3]);
assert_eq!(result, vec![1, 3, 5]);
use lowdash::drop_by_index;

let letters = vec!['a', 'b', 'c', 'd', 'e'];
let result = drop_by_index(&letters, &[0, -1]);
assert_eq!(result, vec!['b', 'c', 'd']);
