@bugaevc@floss.social that’s a mistake allowed by the language. Null deref is UB is it not? Calling unwrap() is explicitly telling the program to panic. It’s not really meant for production use. Think of it like todo!()

@idkrn@infosec.exchange * There is not really a UB in languages like Java and Python (you're thinking of C), dereferencing null is well-defined, in Java it will throw a NullPointerException * There is absolutely unwrap (or expect, etc) usage in any serious/realistic Rust code base
