Function Argument References

References are required to send the value of a variable to a function and still be able to use the original variable afterwards.

That looks like this:

SOURCE CODE

fn main() {
  let alfa = String::from("apple");
  widget(&alfa);
  println!("alfa is {alfa}");
}

fn widget(thing: &String) {
  println!("widget got {thing}");
}
