Generic Const Args and You
Summary
Rust's Inside Rust post introduces Generic Const Arguments (GCA) to expand Const Generics, detailing a family of features (gca_adts, gca_const_items, minimal const items) and how they let you express more complex constants. It also covers ergonomics (macroless options), examples for ADTs, arrays, and tuples, and discusses stabilization status and future work.
