- Rust's compiler team is working on a next-generation trait solver to improve type inference and trait resolution.
- The new solver aims to simplify future changes, fix soundness bugs, and provide faster compile times.
- It handles complex cases like self-referential trait implementations that cause cycles in the current solver.
- The rewrite uses caching and canonicalization to speed up compilation and improve error messages.
- Currently experimental, it's used for coherence checking in stable Rust and can be tested globally in nightly builds.
