Rust's Unsafe Code Guidelines Reference
This document is a past effort by theUCG WG to provide a "guide" forwriting unsafe code that "recommends" what kinds of things unsafe code can andcannot do, and that documents which guarantees unsafe code may rely on. It islargely abandoned right now. However, theglossary is activelymaintained.
Unless stated otherwise, the information in the guide is mostly a"recommendation" and still subject to change.
