Normalize after substituting via `field.ty()` Back in https://github.com/rust-lang/rust/issues/72476 I hadn't understood where the problem was coming from, and only worked around the issue. What happens is that calling `field.ty()` on a field of a generic struct substitutes the appropriate generics but doesn't normalize the resulting type. As a consumer of types I'm surprised that one would substitute without normalizing, feels like a footgun, so I added a comment. Fixes https://github.com/rust-lang/rust/issues/89393. |
