   Wrote a dinky little multithreaded chat server in Tokio, wasn't too hard.

   I did it using standard mutex/lock code to learn how it works, but typically prefer lockless code using pipes / actors. I think it suits the way I think about problems better, even if it is an abstraction

   It did make me wonder something about Rust, specifically how to avoid copies

     @aer I found this post enlightening: https://jacko.io/object_soup.html

     Mainly, my "database" is just a bunch of hashmaps in a struct. HashMap<i32, User>, HashMap<String, Room> etc

     What I don't get is, how do I implement a get_user function such that it returns a read-only reference to a User, as opposed to a cloned User object?

     I keep running into scoping/lifetime issues, and I get it. Realistically my Storage struct has a static lifetime, so it /should/ be fine, but the compiler doesn't know that

     Do I have to return an Rc?

     @tek Oh awesome, thanks

     Yeah coming from a dotnet/python background I definitely tend to structure my code this way, and Ruts (and systems code in general) is way less amenable to it, for good reasons

     Definitely a shift in the way of thinking

     @aer For sure. I’m going through the same kind of learnings now after many years of Python.

     @tek Ha, getting towards the end of the article, I was thinking "I think I would use a HashMap", only for him to mention that

     Definitely didn't make the ECS connection, even having used a bit of Bevy. I hadn't considered using an ECS outside of game design but it makes a lot of sense
