I actually got the list from cbindgen's Cargo.lock file. I figured we
were building far more than necessary, since we were throwing almost all
the results.

I wouldn't mind doing it. It'll have to wait until tomorrow though, it's
getting late here.

The motivation behind the 'hidden' part was so they could be public, so
we could keep a list of rust sources in crates-io rather than spread
around, but not visible, since I don't think any of them would build in
their current form.

Not a problem, we can always go back and change them around again later.

Sounds good. I can toss it in.

I knew all the hours I spent banging my head against rust would come in
handy :)
