The `Output` type of the future is `String` because it's the return type of the `example` function. To implement the `poll` function, we use a match statement on the current state inside a `loop`. The idea is that we switch to the next state as long as possible and use an explicit `return Poll::Pending` when we can't continue.

For simplicitly, we only show simplified code and don't handle [pinning][_pinning_], ownership, lifetimes, etc. So this and the following code should be treated as pseudo-code and not used directly. Of course, the real compiler-generated code handles everything correctly, albeit possibly in a different way.

To keep the code excerpts small, we present the code for each match arm separately. Let's begin with the `Start` state: To keep the code excerpts small, we present the code for each match arm separately. Let's begin with the `Start` state:
