GoKawiilRust compiler project nears major 2026 milestones, says contributor
A Rust compiler contributor writes that several long-running initiatives are converging in 2026, including the next-generation trait solver, a reimplementation of core type-system logic nearly a decade in development, and Polonius, a new borrow checker implementation. The author also notes renewed progress on compiler performance after what they describe as one to two years of stagnation.
