[`missing_fields_in_debug`]: make sure self type is an adt Fixes #11063, another ICE that can only happen in core. This lint needs the `DefId` of the implementor to get its fields, but that ICEs if the implementor does not have a `DefId` (as is the case with primitive types, e.g. `impl Debug for bool`), which is where this ICE comes from. This PR changes the check I added in #10897 to be more... robust against `Debug` implementations we don't want to lint. Instead of just checking if the self type is a type parameter and "special casing" one specific case we don't want to lint, we should probably rather just check that the self type is either a struct, an enum or a union and only then continue. That prevents weird edge cases like this one that can only happen in core. Again, I don't know if it's even possible to add a test case for this since one cannot implement `Debug` for primitive types outside of the crate that defined `Debug` (core). I did make sure that this PR no longer ICEs on `impl<T> Debug for T` and `impl Debug for bool`. Maybe writing such a test is possible with `#![no_core]` and then re-defining the `Debug` trait or something like that...? changelog: [`missing_fields_in_debug`]: make sure self type is an adt (fixes an ICE in core) r? `@Alexendoo` (reviewed the last PRs for this lint) |
