This sounds like a great example of where you might want a union (https://doc.rust-lang.org/1.56.0/reference/items/unions.html)



Ooh I forgot the language had those!

I still feel like this trick has it's place though, as an example take a look at where I stole this trick from, by matklad [0] and tell me what you think :)

I think that this code is acceptable as long as you're careful. And I wish Rust had a `#[derive(TryFrom)]` sort of thing for deriving conversions from the declared primitive type to the enum.
