This. I have read the guide a few times through the years, it's such an interesting dive, specially if one follows the programming exercises... I must admit that any time I work with Tokio or other message passing libraries I end up doing some sort of majordomo, I do not know if this is food, but MDP got stuck in my mind for better or for worse... For example with Tokio mpsc I end up creating majordomo coordinator, clients and services in separate threads, I don't know if this good tbh but it's just so easy to split (and so easy to shoot myself in the foot with synchronize shutdown across threads). Do you know of other guides like this?
