RUST COMPILER SHIPS PRIVACY CACHING WIN, LEGACY INT MODULES FULLY DEPRECATED

The compiler just got faster on privacy checks while the standard library closes the book on deprecated integer modules that have lingered for years.

A performance rollup merged overnight that caches already-checked types in the privacy visitor [1], skipping redundant walks through the same interned types across multiple nodes. This targets a real bottleneck where the privacy checker was re-walking identical type structures repeatedly. Separately, std::u8 and friends are now fully deprecated [2], completing the deprecation cycle started years ago and clearing a long-standing cleanup task from the libs roadmap. The compiler team also landed a trait solver fix that normalizes aliases before generalization in the new solver [3], subtly changing how inferred types relate to associated types. On the docs front, docs.rs improved 404 pages for missing rustdoc resources [4], replacing generic errors with contextual recovery links to the crate root and version list. The blog repo picked up three new posts: an official LLM policy framing piece [5], a Polonius alpha enablement announcement [6], and a funding team progress update [7], signaling active communication on governance and project direction.

Action items

→ Review deprecated integer module migration path if your crate uses std::u8, std::i32, etc. rust-lang/rust [plan]
→ Watch Polonius alpha post for testing guidance if you hit borrow checker issues rust-lang/blog.rust-lang.org [monitor]
→ No immediate action needed on compiler changes; performance and solver fixes roll automatically rust-lang/rust [monitor]
