Deriving Traits

You can let the compiler derive a number of traits:

1. #[derive(Debug, Clone, PartialEq, Eq, Default)]
2. struct Player {
3. name: String,
4. strength: u8,
5. hit_points: u8,
6. }

8. fn main() {
9. let p1 = Player::default();
10. let p2 = p1.clone();
11. println!("Is {:?}\nequal to {:?}?\nThe answer is {}!", &p1, &p2,
12. if p1 == p2 { "yes" } else { "no" });
13. }
