How to reverse a Rust slice?

// plain

Reversing a Rust slice can be done using the reverse() method. This method is part of the std::slice module.

Example code

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

Output example

[4, 3, 2, 1]

Code explanation

• let mut my_slice = [1, 2, 3, 4];: This line declares a mutable slice my_slice with elements 1, 2, 3, and 4.
• my_slice.reverse();: This line calls the reverse() method on the my_slice slice, which reverses the order of the elements in the slice.
