X-Proofpoint-GUID: jJiYEABZVGVUxr5IBzuwEcl3XJ7YSe5A +cc Alice - could you help look at this? It seems I have broken the rust bindings here :) Thanks!

Thanks much appreciated :) It seems I broke the rust bindings (clearly), have pinged Alice to have a look! May try and repro my side to see if there's something trivial that I could take a look at. I ran this through mm self tests, allmodconfig + a bunch of other checks but ofc enabling rust was not one, I should probably update my scripts [0] to do that too :) Cheers, Lorenzo [0]:https://github.com/lorenzo-stoakes/review-scripts
