enum Error

[rbtcollins]

Describe the Bug

an Enum called Error casses an assertion in wasm-bindgen

Steps to Reproduce

I haven't done a minimal reproduction yet, but commenting out the following enum in my source fixed the assertion...

#[wasm_bindgen]
#[derive(Clone, Copy, Debug, PartialEq, Eq)]
pub enum Error {
    BadRounds,
}

If applicable, add a link to a test case (as a zip file or link to a repository we can clone).

Expected Behavior

No assertion

Actual Behavior

Thanks for the report, and sorry for the delay in getting to this!

I unfortunately won't have a chance to look at this in the near future, but I suspect that this isn't playing well with the js_sys::Error type. It's probably best to rename enum Error for now, but this probably isn't the hardest thing to handle after some investigation into the CLI!

Got the same problem with enum named Element. Renaming it solved problem. Maybe if we put on line 161 check like on line 149, we could fix this problem.
