I wish the author had gone a bit more in depth on the doubly linked lists and recursive data structures. Those are enormous pain points when trying to do conventional low level programming in Rust, and doing it right the first time might help avoid the pitfall of 'build 90% of what you want, realize you need to redo everything because there's an ownership issue you need to hack around, give up on Rust.'
