await

suspend fun <T> Promise<T>.await(): T

Awaits for completion of the promise without blocking.

This suspending function is cancellable. If the Job of the current coroutine is cancelled or completed while this suspending function is waiting, this function stops waiting for the promise and immediately resumes with CancellationException. There is a prompt cancellation guarantee. If the job was cancelled while this function was suspended, it will not resume successfully. See suspendCancellableCoroutine documentation for low-level details.
