I am studying Combine with the book, and I have questions on Chapter 18.
- There is a description like below, and I can not understand what it means. Specifically on bold text.
- Use the handy AnySubscriber class which takes closures, and immediately request .unlimited values upon subscription to let the publisher run to completion.
Why does the publisher run to completion when I use .unlimited?
- And there is the other description like,
Note: You could initially request .max(self.capacity) and receive just that, but remember that Combine is demand-driven! If you don’t request as many values as the publisher is capable of producing, you may never get a completion event!
I’m just curios why I can’t get completion when using .max(n).
If I set .max(2), I can get completion after getting two values. Can’t I?
