So far on small ARM devices - yes. I run on beaglebone, looking deeper at stm32 and other cortex M boards as well. Arduino is less likely though. Cortex M is really micro-controller only Cortex - A for sure no prob, an interesting one will be the cortex R for Iot type devices. If anyone was tinkering there then we would be onto something. For this I am following rust zinc as an easy way forward (stm32 OK there for basic micro-controller apps) zinc will make it easy if it gets to cortex R for sure.,
