Is there some sort of dispatch_once in the Kotlin Coroutine world?

[marstran]

What do you mean?

[antonis]

dispatch_once is basically used to create singetons, right?

[Alessandro Diaferia]

I guess I’m looking for a compact way of doing

val someSetupJob by lazy {
    async {
        // do some complex initialization
    }
}

[antonis]

you can do that with the object keyword

[antonis]

val myLazyValue = async(start = CoroutineStart.LAZY) { ... }. Use myLazyValue.await() when you need it
