Mathieu and Jason are joined by Jon Bauman to discuss safety and interoperability between Rust and C++. They dig into what "safety" really means (there are several categories of safety), what can and can't be guaranteed, how C++ could become a memory-safe language, and the challenges of making Rust and C++ work well together. Jon is currently looking for sponsorship to continue this important work. You can contact Jon via Joncppcast@shumi.org.
