You talked about using Rust as a better C so I just wanted to ask, do you define any enums with payloads? (also called "sum types" or "tagged unions" in other languages) (edit: also called "algebraic tyeps" and there's an article about it in the front page, though this is a slight misnomer)

Things like

    enum Something {
        One(String),
        Two(i32),
    }

Also, how is your usage of Option? (one such enum)

I think this plus pattern matching is the foundation of Rust's superpowers. It's also very old tech and absolutely not Rust's invention, present in languages like OCaml and SML. Hence the early Rust slogan, "technology from the past, come to save the future from itself"
