When building on Linux, the build fails:

Seems that bindgen is generating some duplicate bindings then fails to build.

I was able to build by updating build.rs to this: https://github.com/amanusk/class-groups/blob/fix-duplicate-bindings/build.rs Need to make sure this does not break anything

cool thanks. Can you also submit a PR? I will check if the mac build breaks or not
