It is similar to Guava's AsyncFunction, redeclared so that Guava can be shaded.

Methods
apply(I input)
publicabstractApiFuture<O>apply(Iinput)
Returns an output Future to use in place of the given input. The output Future need not be
done, making AsyncFunction suitable for asynchronous derivations.
Throwing an exception from this method is equivalent to returning a failing Future.
