// Copy Types vs. Move Types

// Instances of data that are easily copyable (and relatively cost free)
// Such as all of the primitive numeric types, or a char.
// are simply copied into places where types would otherwise be moved.

// The rules for borrowing a copy type remain exactly the same.

fn copy_and_display(x: i32) {
    println!("x = {}", x);
}

fn move_and_display(s: String) {
    println!("s = {}", s);
}

fn main() {
    let x = 5;
    copy_and_display(x);

    // We can still print x, because it was copied into the function, not moved.
    println!("x = {}", x);

    let s = String::from("this is a move type");

    move_and_display(s);

    // We can no longer display s because it was moved into the function.
    // println!("s = {}", s);
