The `Debug` impl for `Ty` just calls the `Display` impl for `Ty`. This is surprising and annoying. In particular, it means `Debug` doesn't show as much information as `Debug` for `TyKind` does. And `Debug` is used in some user-facing error messages, which seems bad. This commit changes the `Debug` impl for `Ty` to call the `Debug` impl for `TyKind`. It also does a number of follow-up changes to preserve existing output, many of which involve inserting `with_no_trimmed_paths!` calls. It also adds `Display` impls for `UserType` and `Canonical`. Some tests have changes to expected output: - Those that use the `rustc_abi(debug)` attribute. - Those that use the `EMIT_MIR` annotation. In each case the output is slightly uglier than before. This isn't ideal, but it's pretty weird (particularly for the attribute) that the output is using `Debug` in the first place. They're fairly obscure attributes (I hadn't heard of them) so I'm not worried by this. For `async-is-unwindsafe.stderr`, there is one line that now lacks a full path. This is a consistency improvement, because all the other mentions of `Context` in this test lack a path. |
