Enhancing Unsafe Rust: Compile-Time Error for MaybeUninit UB — Rust Internals
A new proposal in Rust Internals aims to prevent undefined behavior (UB) in `MaybeUninit` by introducing compile-time errors. This experiment extends support for arrays, structs, and enums, introducing a new write function to ensure safe usage. By catching potential UB at compile time, Rust developers can write safer code without runtime penalties, enhancing the robustness of unsafe Rust codebases.
