If I were to read a book about rebuilding a car engine, I wouldn't feel comfortable with actually doing so. Experience remains necessary to reach that comfort level. Define concrete goals with learning any language and that will help you measure progress. Rust is a massive language with many features that aren't required learning in order to accomplish many types of development. Over time, you'll probably learn them out of curiosity and continued personal development. You'll also return to code that you seek to optimize.
