Explore the concept of "class fixes" in this RustConf 2019 talk by Isobel Redelmeier. Discover how Rust's features, particularly the borrow checker, provide solutions that address multiple problems simultaneously. Learn to think like the Rust compiler and apply its rigorous approach to code correctness in non-Rust projects. Gain insights into holistic debugging and system design techniques that can be applied across various programming languages and environments. Walk away with a enhanced toolkit for identifying and implementing class fixes in your own development work.
