12.1 Enumerated type

An enumerated type defines a fixed size set of possible values. It is declared using the enum keyword.

Here is an example that defines the card suits:

:clear

#[derive(Debug)]
enum Suit {
  Club,
  Diamond,
  Heart,
  Spade,
}

for x in [Suit::Diamond, Suit::Club, Suit::Heart, Suit::Spade] {
  println!("{x:?}");
}

Diamond

Club

Heart

Spade
