Excelent thank you for this, yes we can certainly use your help with
this. After this went out we also had Daniel Gomez express interest, and
Petr Pavlu expressed interest as well. I think with all of us we can
likely grow a strong base to cover both C / Rust side of modules.

I'll send a follow up maintainers patch up for this and we can move on
forward with review / future integration of Rust module code.
