## Summary

A practical guide to introducing Rust into an existing C++ codebase using the `cxx` crate. Covers setting up the `#[cxx::bridge]` macro, declaring opaque types, exposing Rust methods to C++, handling limitations like consuming methods and unsupported types, and generating C++ bindings via `cxx-build`. Includes a working CRC32 hashing example with a C++ main function calling Rust code, plus a deep dive into the macro expansion to understand how `cxx` enforces safety at the FFI boundary.
