What is the difference between actor model and fan out from the guide? <https://github.com/Kotlin/kotlinx.coroutines/blob/master/docs/channels.md#fan-out>

`actor` is the opposite direction, right? it receives objects, instead of sending them

<https://kotlinlang.org/docs/reference/coroutines/shared-mutable-state-and-concurrency.html#actors>

Right - so the actors == worker coroutines from fan out model?

sort of, but there's only one of them -- you can't add more

I'd say actor is an opposite to fan-out in a sense that it can be used as a fan-in -- you send messages to it asynchronously, from different contexts, and it processes them serially.

It's basically a channel with a coroutine consuming from it attached.
