Some API suggestions:)

Very professional suggestions! 👍 🚀 @He-Pin

1. Provides an extension definition for Kotlin ?

Yes! Kotlin extension methods are amazing, a MUST have. 🎊

2. Provides an extension for Vertx Function?

Wish to keep cffu only concern CompletableFuture, and be a tiny sidekick lib of CompletableFuture. 🚸

VertX is another (full-fledged) concurrency framework.

3. How about keep the Cffu a clean room, and not extends the Future and CompletionStage directly, but provides methods like fromCompletionStage and toCompletionStage.

Good design idea! 🚀

Wish Cffu to drop-and-replace CompletableFuture as much as possible, so Cffu extends the Future and CompletionStage instead provides methods like fromCompletionStage and toCompletionStage.

4. then we can have method like failed instead of failedStage.

Same reason as above.

Hi @He-Pin

this commit(66e06dc) has added a Kotlin extension method:

public <T> Cffu<T> asCffu(CompletionStage<T> stage)
