@elizarov Just out of curiosity - how does one go about adding support for 'suspend' functions to their own interface of their library - dunno if the question makes sense --- https://twitter.com/JakeWharton/status/964556938322341894

What do you mean? Of course only one who wants to use suspend Retrofit method would add it to interface. This tweet about support of such approach from side of Retrofit

Right yeah thats what I mean - what would the support from retrofit's side look like

Retrofit uses reflection and creates Proxy instances. So I suppose it should somehow detect suspend functions and generate proper Proxy instance for suspend functions

Yes, that. It's a mechanism for detecting the Continuation parameter and hooking it up.

In a general way? What do you mean? Allow to support not only kotlin.coroutines Continuations?

Retrofit 1 allowed a callback as the last parameter of a method signature. So the idea is to build a mechanism similar to CallAdapters that allows adapting the last parameter into another type.

I see. And then just provide this parameter adapter for coroutines continuation
