Kovenant

The easy asynchronous library for Kotlin. With extensions for Android, RxJava, JavaFX and much more.

task {
    //some (long running) operation, or just:
    1 + 1
} then { 
    i -> "result: $i"   
} success { 
    msg -> println(msg)
}

Developed with the following goals in mind.

Easy to use: Function above anything else
Runtime agnostic: API layer must be pure Kotlin
Memory efficient: trying to reduce the overhead as much as possible
Non blocking: besides being thread safe everything should be non blocking (JVM)
Dependency free: when not counting kotlin std
