Hi, it's nice to have a callback mechanism on the latest pubsub client library, but it would be even better if the RPCFuture.addCallback supported functional interfaces instead of an interface with two methods to process errors and success.

so if instead of addCallback(RpcFutureCallback)

public void subscribe(Consumer success, Consumer<? super Throwable> error){

One could just invoke the subscribe with lambdas expressions.

I know Consumer is Java 8 construct, but any functional interface with an interface like

Foo{

void apply(T t)

}

would work

Unfortunately, we probably aren't going to do this. We are trying to match the patterns of ListenableFuture from Guava, which is well-established and widely understood. When we migrate to Java 8, we will fully use the available Java 8 constructs.
