error: could not compile `bindgen-test-case`
Expected Results
I'd expect the type of contents_ to be a c_int.
Other notes
Perhaps this counts as the "traits templates" situation listed under the recorded C++ limitations but, as it doesn't involve any nasty SFINAE magic I am hoping this may be possible.
Thanks for bindgen, it's amazing! Apologies if this is a duplicate.
