There was a problem hiding this comment.
That's a cool idea I hadn't even though of, to check if the output types match with either Option or Result. 👍

Just one possible improvement, otherwise this looks good to me. |
Check the return type of `len`. Only integral types, or an `Option` or `Result` wrapping one. Ensure the return type of `is_empty` matches. e.g. `Option<usize>` -> `Option<bool>`
