…, r=BoxyUwU Suppress copy impl error when post-normalized type references errors Suppress spurious errors from the `Copy` impl validity check when fields have bad types *post*-normalization, instead of just pre-normalization. ---- The const-generics test regressed recently due to rust-lang#107965, cc `@BoxyUwU.` * I think it's because `[_; 0u32]: Copy` now fails to hold because a nested obligation `ConstArgHasType(0u32, usize)` fails. * It's interesting that `[const_error]` shows up in the type only after normalization, though, but I'm pretty sure that it's due to the evaluate call that happens when normalizing unevaluated consts.
