Type Parameters:

T - the upstream type

R - the output type

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface MaybeConverter<@NonNull T,@NonNull R>
```
Convenience interface and callback used by the Maybe.to(io.reactivex.rxjava3.core.MaybeConverter<T, ? extends R>) operator to turn a Maybe into another value fluently.
