rustHow to get the last element of a Rust slice?

The last element of a Rust slice can be accessed using the .last() method. This method returns an Option<&T> where T is the type of the elements in the slice.

Example code

let v = [1, 2, 3];
let last = v.last();

Output example

Some(&3)

Code explanation

• let v = [1, 2, 3];: This line creates a slice v with three elements.
• let last = v.last();: This line calls the .last() method on the slice v and stores the result in the variable last.
