Yeah regardless of time taken the study plan for Rust already exists (https://doc.rust-lang.org/book/). You don't need ChatGPT to regurgitate it to you.

The book is great but its not really helpful for teaching.

To get to a reasonably proficient level in rust I did the following.

1. Use the book as the reference.

2. Angela Yu's 100 days of python has a 100 projects to help you learn python (highly recommended if you want to learn python). Tried creating those projects from scratch in Rust.

3. I'd use the book as a reference, then chatGPT to explain more details why my code is not working, or which is the best approach.

The key points that helped me, besides correlating sections to the corresponding chapters in the book, are the proposal of certain exercises every week to cover the topics we've seen and the encouragement to write small articles around the lessons. I've already completed the Rustlings independently before this but it left me kind of lopsided and wanted to make this knowledge as full as possible.
