If you have a little bit of experience with any higher level language (eg Python, Haskell), then I'd say fairly quicky (say, a week to a week and a half for the books and rustlings course), if you want an opinionated (and good enough, I recommend the book!) intro to production code theres the zero2prod Rust book. You can read the zero2prod book while working on one or two pet project (anything more complicated than a calculator would probably do) to help inform decisions. That should be another week or two, depending on how quickly you pace through the book. That should get you started to writing decent code, maybe not aways idiomatic or neatly structured. That might take a few more weeks or months (depending on your interest domains and their inherent complexities). But like with all skills, it's an endless journey; you'll keep getting better as you're increasingly more familiar with the tools.
