This isn't a tutorial, but a tip that has helped me a lot today. In Architecture Suggestions for Idiomatic Rust - #5 by RustyYato, I was having difficulty "thinking" in rust and @RustyYato advise me to think in terms of "borrowing" instead of mutability.
I took that suggestion to heart and wrote out, in natural english, what my code was doing. I was sure to use the terms "borrow", "lend," "give ownership to," and "take ownership of." It was really enlightening. I normally just think about where an object is and don't care about how or why its there.
Anyway, it's helped me so I thought I'd pass it along.
Any other tips for newcomers?
