Description

I have a wrapper.h that wraps a C library called foo and looks like this:

#include <foo/a.h>
#include <foo/b.h>

Currently bindgen dumps everything into the top of my crate. I'd like the code generated by bindgen to instead produce two modules pub mod a; and pub mod b; and expose that instead.

Research direction

Start with the wrapper.h example and trace how bindgen currently handles the included foo/a.h and foo/b.h headers. Identify the entry point responsible for emitting declarations and determine how separate public modules should be represented. Done means the generated bindings expose a and b as distinct public modules rather than placing everything at the crate root.
