rustHow to get the last element of a slice in Rust?

The last element of a slice in Rust can be obtained 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)

The .last() method returns an Option<&T> which is an enum with two variants: Some(&T) and None. If the slice is empty, None is returned, otherwise Some(&T) is returned where T is the type of the elements in the slice.
