I guess it would have been nice to have a

getCompletedOrNull()

that returns a null instead of throwing... so currently the only way is to

runCatching { deferred.getCompleted() }.getOrElse { defaultValue }

You can check

isCompleted

instead

if(deferred.isCompleted()) getCompleted() else defaultValue

So here's your

poll

method:

fun <T: Any> Deferred<T>.poll() = if (isCompleted) getCompleted() else null
