Here's some advice I've given about learning Rust in the past. https://news.ycombinator.com/item?id=38020654

There are also project-based resources beyond Rustlings like Entirely Too Many Linked Lists[1] you might check out. I've found Gjengset's videos[2] great for intermediate content, and they include both project and lecture formats.

Best of luck!
