If the returned value is still valid despite an error, then the function would return (u32, Option<Error>), perfectly valid rust. If the value is meaningless in case of an error then using it is incorrect code; you wouldn't want to do that in either language and rust makes that assumption explicit with unwrap. If you want a default value in case of error just use unwrap_or_default.
