Effectively:
- Move the previous bindgen script into build.rs
- In lib.rs, include the file generated at build time
- Compile inline statics with devkitARM toolchain
- Remove now-unneeded reimplementations of inline statics
- Use doxygen_rs to clean up the docs of the generated bindings.
Nice! This cleans up the repo a lot and also ensures we are using the
canonical implementations of those inline functions, which should help
prevent mistakes as well.
