Trickle: Spotify's library for composing asynchronous code in Java

I much prefer the Android Annotations [1] approach to asynchronous functions, but I&#x27;m not sure they are solving exactly the same problem. Can anyone comment?<p>[1] <a href="https://github.com/excilys/androidannotations/wiki/WorkingWithThreads" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;excilys&#x2F;androidannotations&#x2F;wiki&#x2F;WorkingWi...</a>

This looks promising. The syntax is a bit clunky, however. How would this look with Java8 and lambdas?

Interesting idea, but my eyes bleed. And I&#x27;m a Java programmer. Would rather use Akka or SlicedBread (the latter trading almost all features for the added simplicity but working well and being super-simple).

I&#x27;m curious — how does this deal with errors in async calls? RxJava has error handling built in with `onError` functions.

... or just use NodeJS instead.
