I use it for almost anything that it works with, except maybe web stuff. If I want to write a project, I'm most likely gonna use Rust for it. I've done web servers, cli tools, graphics/"game dev", a Listenbrainz discord RPC daemon (tho that's broken now), and a library for actix session using surrealdb that's actually got some users for some reason. Oh and web stuff is absolutely possible, but with WASM having to use glue JS for DOM calls, u get all the negatives of using a technology for something unintended without any of the benefits.
