janriemer, 1 year ago Oh wow, did you know that in #Rust you can use Option as an iterator such that your types align, when you want to return a chain of iterators from a function, but also have an else case where the iterator is empty!? I know, this was a mouthful.😳 Let's look at a playground that shows this: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=129eb419d767b71447b408e456773555 This trick is right from the docs on option: https://doc.rust-lang.org/stable/std/option/#iterating-over-option What a cunning trick!🤓 Rust, I ❤️ you! #RustTip #RustTips #RustLang
