I’m currently reading Rust Brain Teasers by Herbert Wolverson. It’s a nice book of bite-sized puzzles in Rust that are ideal for the way I like to learn (randomly jumping around from subject to subject that happen to interest me). Each puzzle presents some code, asks you what you think it does and then shows you the hidden complexity. At the end of each section are some links to further reading.
I’m currently reading Rust Atomics and Locks by Mara Bos and it’s excellent. Really approachable, concise and detailed. A pleasure to read.
