The detection of slice reference of
{integral}inrustc_on_unimplementedis hacky, but a proper solution requires changingFmtPrinterto add a parameter to print integers as{integral}and I didn't want to change it just forrustc_on_unimplemented. I can do that if requested, though.I'm open to better wording; this is the best I could come up with.
