> the only synchronization issue is between interrupts and main program, a case rust doesn't handle afaik(?) and in 99% of the cases a ring buffer or simple flag variable is enough. I'm not sure what you're expecting it to handle that it isn't. That static flag or ring buffer needs synchronization and rusyc will absolutely not let you forget that (in safe code). One technique you get in Rust that's very compelling for embedded is using traits, especially when implemented on zero-sized types, to cleanly express configuration. Personally I abhor all those one-off table generating scripts.
