Function drop_right 

pub fn drop_right<T>(collection: &[T], n: usize) -> Vec<T>
where
    T: Clone,

Removes the last n elements from a collection and returns the remaining elements. If n is greater than or equal to the length of the collection, returns an empty Vec.

Time Complexity: O(1) for slicing; O(m) for cloning, where m is the number of elements after dropping.

Arguments

• collection - A slice of items from which elements will be dropped.
• n - The number of elements to drop from the end of the collection.

Type Parameters

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

Returns

• Vec<T> - A vector containing the elements after dropping the last n elements.

Examples

use lowdash::drop_right;

let numbers = vec![1, 2, 3, 4, 5];
let result = drop_right(&numbers, 2);
assert_eq!(result, vec![1, 2, 3]);

use lowdash::drop_right;

let letters = vec!['a', 'b', 'c', 'd'];
let result = drop_right(&letters, 10);
assert_eq!(result, vec![]);
