If you like TDD, checkout rustlings https://github.com/rust-lang/rustlings/. I'd recommend https://exercism.io/, but there's such a shortage of mentors for the Rust track that you can get blocked very easily waiting for feedback. One of my solutions went un-mentored for over a month - and it was only after I asked someone directly to mentor my solution that it passed. If that weren't a problem, I would highly recommend exercism.io
Unfortunately, the code examples in the Rust book still feels like toy projects / toy code.
What I like about the Go book is that it feels production-ready, even though it is simple. This is because it is following industry best practices. There's no "code in isolation", if that makes sense.
Coming from a background in scripting languages, Rust is still a lot more difficult to learn than Go, but I found that book very helpful.
