Hey @rustlang folks! Any way of converting a c-like bitflag enum to an integer type. Doing ‘as u16’ doesn’t seem to work.

Hmm, it should work: https://rustbyexample.com/custom_types/enum/c_like.html …

Here is my actual case, I try to do a .map(|v| v as u32) where v is of my enum type. And there i can’t seem to cast, because of ref?

It looks like the issue if the ref. I will investigate more. Thanks for the tip!

Replying to @ozkriff
Tried that, and ‘Can’t move out borrowed value’. My current solution is to clone and cast. That seems wrong though

Sounds like you need `#[derive(Clone, Copy)]` on the enum

Yep, that was exactly that. I don’t really understand why they are needed though. Is it copying the value out of my iter?

If you do `.iter`, that iterates over references to each element. To take the value out requires a copy. `.into_iter` takes ownership

Hum. That make sense. Thank you!

Distinction really only matters for non-Copy types. Since your type is copy, it's just an extra `&` or `*`
