I came here to say almost the same thing. I've been learning rust in my free time because I don't do enough programming at work to scratch that itch any more, and I've been using the rust book as a reference.

Thanks for the rec for "rust for rustaceans" I'll have a look into it.

I've only been using chatgpt for points where i'd normally go ask another dev for another set of eyes to debug something, otherwise all my learning and doing has been mostly the rust book, crates, and blogs about rust, ecs, roguelikes etc etc. It's been so fun!
