Sure, I am open to any approach here. Although this looks a bit reversed to me.

i.e.: why should I declare these structs in a separate language and file, and then use them in Rust through bindgen? Sounds clunky.

Right now, they are declared right next to where they are used in the code, i.e.: in the same Rust file. And so long as they’re #[repr(C)] we know that an equivalent C version can generated by cbindgen.
