Rust is not a FP language. It's an imperative language with restricted state and a few FP constructs included.
To me what makes a language FP is the mindset and that boils down to deciding to fold instead of loop and you lean to closure captures instead of declaring variables. Both sides of these are basically equivalent but having a function as the big hammer you use to nail everything together is what makes it functional programming instead of X programming with some functional ideas carried over.
When people structure a request like this they're generally after a way to really get into the ideas and the best way to do that is to use a language that's built around FP ideas. I personally recommend Clojure and OCaml. If you'd like to do Scheme via the Wizard book then that's fine as well. I don't really like the pure functional languages (Haskell and friends) because I think that state is a useful thing in small doses and don't like jumping through the extra hoops to get at it.
