kotlinlang

looking at the docs for <https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-jdk8/kotlinx.coroutines.future/await.html>
can some one explain what does “one-shot future” mean in this context. It’s not clear to me when one should use `.await()` vs `.asDeffered().await()` .

It means you started the future for use in a single spot like `startFuture().await().` If this await is cancelled, nothing else will use the future so it's safe to cancel. Use `asDeferred().await()` if the future is stored and used elsewhere or if it causes side effects that you still want even if the awaiting coroutine is cancelled.
