Example of typestates in Rust using generics
trait DoorState {}
// PhantomData is a zero-sized type that tells the compiler to pretend that
// Door actually stores a value of type State, since otherwise we'd get an
// unused type parameter error.
struct Door<State: DoorState> { number: u8, state: std::marker::PhantomData<State> }
// Our states don't actually hold any data. If they did, we wouldn't need
// PhantomData.
