zip9<R, A, B, C, D, E, F, G, H, I> function

EventSubscriptionBuilder<R> zip9<R, A, B, C, D, E, F, G, H, I>(EventSubscriptionBuilder<A> eventA, EventSubscriptionBuilder<B> eventB, EventSubscriptionBuilder<C> eventC, EventSubscriptionBuilder<D> eventD, EventSubscriptionBuilder<E> eventE, EventSubscriptionBuilder<F> eventF, EventSubscriptionBuilder<G> eventG, EventSubscriptionBuilder<H> eventH, EventSubscriptionBuilder<I> eventI, R zipper(A a, B b, C c, D d, E e, F f, G g, H h, I i,),)

Zips the values of each provided event using the zipper into a single output EventHandler when all handlers have emitted at each index.

See zip.
