In order to use suspend functions retrofit 2.6.0

I found this test really helpful: https://github.com/square/retrofit/blob/master/retrofit/src/test/java/retrofit2/KotlinSuspendTest.kt#L233

In your case, you will be delegating to the call obtained from the nextCallAdapter::adapt. And If I am reading it correctly, make sure that that nextCallAdapter uses rawResultType, and not the returnType, because you want the default call adapter to handle the Call<T> and not the Call<Results<T>>

[leodeleon]

My main doubt is what do do on adapt to get Result<T>

[Vlad]

Wrap the call of Call<T> from the nextCallAdapter::adapt in an implementation of Call<Results<T>> where the override fun enqueue() will enqueue the adapted call and wrap into the Results and will pass the wrapped response to its callback. The rest of the Call methods can be delegated to the adapted Call<T>

[leodeleon]

still can't compile tho

[leodeleon]

I'm sorry for my ignorance, I'm almost there

I'm wrapping the call, but the return types don't match and I still don't know how to communicate back the Results<T>
