By far the biggest changes to Rust in recent times are non-lexical lifetimes (IIRC, introduced in the 2018 edition), and async functions (introduced in Nov. 2019). So if you're reading any introductory material after Nov. 2019, or anything after 2018 that isn't related to asynchronicity/futures/etc., it'll be reasonably similar to modern code.
