@RequiresApi(value = 31)
public static final @NonNull OutcomeReceiver<@NonNull R, @NonNull E> <R extends Object, E extends Throwable> asOutcomeReceiver(
    @NonNull Continuation<@NonNull R> receiver
)

Returns an OutcomeReceiver that will resume this Continuation when an outcome is reported.

Useful for writing suspend bindings to async Android platform methods that accept OutcomeReceiver:

public suspend fun FancinessManager.query(
    query: FancinessManager.Query
): FancinessManager.QueryResult = suspendCancellableCoroutine<QueryResult> { continuation ->

    // Any Android API that supports cancellation should be configured to propagate
    // coroutine cancellation as follows:
    val canceller = CancellationSignal()
    continuation.invokeOnCancellation { canceller.cancel() }

    // Invoke the FancinessManager#queryAsync method as follows:
    queryAsync(
        query,
        canceller,
        // Use a direct executor to avoid extra dispatch. Resuming the continuation will
        // handle getting to the right thread or pool via the ContinuationInterceptor.
        Runnable::run,
        continuation.asOutcomeReceiver()
    )
}
