You still have to be a bit careful about finding old posts and old docs on the internet about Rust, given that many APIs have only been stable for a short while. In general, unless you know your source is up to date, I'd recommend ignoring the internet at large completely when it comes to Rust APIs and just focusing on the official docs for the release that you're using. They're plenty good enough, though you do have to get used to navigating them.
