Fuel: How to merge requests

[GavinDon]

like retrofit can use merge Operator Make multiple requests

[SleeplessByte]

Retrofit can actually not merge requests by itself. When using an extension, such as RxJava with retrofit, "merging" requests is done with that.

LiveData

https://developer.android.com/reference/android/arch/lifecycle/MediatorLiveData

You can use a MediatorLiveData and two Fuel to livedata calls to get a live data that responds when both are done.

RxJava

You can use the same interface as in Retrofit to merge two Fuel to Observable calls.

Coroutines

You can make a new suspending function that awaits two things:

fun suspend both(){
  ...deferredCallOne
  ...deferredCallTwo

  val resultOne = deferredOne.await()
  val resultTwo = deferredTwo.await()
  return ...
}

I welcome someone to actually write these out as examples, but "merging two requests", outside the scope of HTTP/2 is not in the scope of Fuel.
