Or better, adapt callbacks to a suspend function to avoid blocking a thread (which is just wasting resources for the cases where you can avoid it)

[antoin_m]

Yeah, that was more or less the purpose of my first question. How would you adapt a Future#get to a non blocking suspend function?

[antoin_m]

I feel like I’m missing something

[louiscad]

@antoin_m There's already an integration module, which doesn't use get but the callback equivalent I think. Look at kotlinx.coroutines repo in the integration directory

[antoin_m]

Ok got it! Thanks 🙂

If you have custom code, you can also use `suspendCoroutine`:

fun callbackFunction(callback: (String) -> Unit) {
  timer(period = 2000) { callback("Hello world") }
}

suspend fun suspendingUsage(): String {
  return suspendCoroutine { continuation ->
    callbackFunction { result ->
      continuation.resume(result)
    }
  }
}
