During December 2025, Utjok developed a feature for the cryspen/libcrux repository that introduced const-evaluated methods within the impl_struct! macro. By refactoring macro implementations to use Rust’s const fn capabilities, Utjok enabled compile-time evaluation of methods, reducing runtime overhead and aligning with Rust’s emphasis on safety and performance. This work focused on macro development and const evaluation, particularly targeting the *-ml-dsa/types modules to convert implementations to const functions. Although no bugs were fixed during this period, the changes enhanced compile-time guarantees and laid the groundwork for further optimizations in critical data structures used throughout the codebase.
December 2025: Delivered a focused feature in cryspen/libcrux that enables const-evaluated methods within the impl_struct! macro, unlocking compile-time evaluation opportunities and potential runtime optimizations. This aligns with Rust idioms for safe, fast code and reduces runtime overhead for critical paths. No major bugs fixed this month, with the primary emphasis on macro design and performance-oriented refactoring. Overall, the work enhances compile-time guarantees and sets the stage for further optimizations in key data structures used across the codebase.
