rustHow to remove the last element of a Rust slice?

The last element of a Rust slice can be removed using the pop() method. This method removes the last element from the slice and returns it.

let mut my_slice = [1, 2, 3, 4];
let last_element = my_slice.pop();

println!("The last element is: {:?}", last_element);

Output example

The last element is: Some(4)

The pop() method takes no arguments and returns an Option<T> where T is the type of the elements in the slice. If the slice is empty, None is returned.

Code explanation

• let mut my_slice = [1, 2, 3, 4];: declares a mutable slice with four elements
• let last_element = my_slice.pop();: calls the pop() method on the slice to remove the last element
• println!("The last element is: {:?}", last_element);: prints the last element to the console
