rustHow to get the end of a slice in Rust?

The end of a slice in Rust can be obtained using the .end method. This method returns an Option<&T> where T is the type of the slice.

Example code

let v = [1, 2, 3, 4, 5];
let s = &v[1..4];
let end = s.end();
println!("{:?}", end);

Output example

Some(&5)

The code above creates a slice s from the array v and then uses the .end method to get the end of the slice. The output is Some(&5) which is the last element of the slice.

Parts of the code:

• let v = [1, 2, 3, 4, 5];: creates an array v with elements 1, 2, 3, 4, and 5.
• let s = &v[1..4];: creates a slice s from the array v with elements 2, 3, and 4.
• let end = s.end();: uses the .end method to get the end of the slice s.
• println!("{:?}", end);: prints the output of the .end method.
