However, others are more conservative and will only start investing into it if we are in mainline, i.e. if the decision of having Rust or not is already taken. But it is fair to ask for a hardware driver to see how it looks like, which is why the cover letter mentions we are working on one. Now, if you are OK with non-hardware modules, you can take a look at Rust Binder (last patch in the series) which is a non-trivial module and it is already working. Cheers, Miguel
