Rust core contributor Yoshua Wuyts outlines his grand vision for Rust's future development, focusing on three key language enhancements: improved effect system support (beyond async/const functions), substructural types for advanced memory management, and refinement types for more precise type constraints. These features would enable stronger guarantees about function behavior like termination, determinism, and panic-free execution, particularly valuable for systems programming domains. The vision represents significant but achievable evolution of Rust's type system capabilities.
Background
Rust is a systems programming language known for its strong memory safety guarantees and expressive type system. The language already supports several 'effect-like' features such as async/const functions, but there's ongoing research to expand these capabilities further.
