Clone types

An alternative to using references is to clone values. By cloning a value, we don't move it. To be able to clone a point, we can add derive to it:

#[derive(Clone, Debug)]
struct Point {
    x: i32,
    y: i32,
}

We can now call the clone() method to avoid moving our p1 point:

fn print_point(point: Point) {
    println!("x: {}, y: {}", point.x, point.y);
}

let p1 = Point { x: 1, y: 2 };
let p2 = p1.clone();
print_point(p1.clone());
println!("{}", p1.x);
