rustHow to get the last n elements from a slice in Rust?

To get the last n elements from a slice in Rust, you can use the .split_last() method. This method takes a slice and returns a tuple of two slices, the first being the elements before the last n elements, and the second being the last n elements.

Example code

let v = [1, 2, 3, 4, 5];
let (first, last) = v.split_last().unwrap();
println!("First: {:?}, Last: {:?}", first, last);

Output example

First: [1, 2, 3], Last: [4, 5]

Code explanation

• let v = [1, 2, 3, 4, 5];: This creates a slice of 5 elements.
• let (first, last) = v.split_last().unwrap();: This uses the .split_last() method to split the slice into two slices, the first being the elements before the last n elements, and the second being the last n elements.
• println!("First: {:?}, Last: {:?}", first, last);: This prints the two slices.
