Rust: Next-Solver Hardening and Attribute Cleanup
The compiler team pushed the new trait solver toward default with crash-test migrations and coherence fixes, while centralizing attribute validation into early parsing. Rustdoc deref handling and codegen correctness fixes round out a reliability-focused day.

Good morning, it's Tuesday, October 6th, 2026.
The through line today is stabilization work: finishing the new trait solver, and cleaning up how the compiler validates attributes.
First, the next solver push. Pull request 163796 continues migrating crash tests to the next solver flag, closing out ten linked issues, and pull request 163806 extends that to dozens more crash cases. That's paired with a correctness fix in pull request 163267 for visibility leak checking in the region outlives…
Second, attribute handling consolidation. Two merges move validation earlier into attribute parsing as part of issue 153101. Pull request 163673 moves doc inline and doc no-inline checks, including conflicting attributes and misuse on non-use targets, while pull request 163787 moves legacy const generics checks with…
Finally, documentation and code generation reliability. Pull request 160915 fixes rustdoc handling of deref, keeping only methods and correctly showing self-consuming methods when the target is copyable. On the backend, pull request 163867 fixes a miscompilation where global value numbering reused references across…
What's next: watch testing on the open next-solver crash batch, plus…
