Possibly. How would you construct said garbage? Would it require unsafe?

I'm not sure, probably yes. It all depends on the winapi crate. If you can get an handle of a different "type" than the expected one, then it's garbage for GetFileInformationByHandleEx. Probably you can't do it without unsafe, so maybe it's fine.
