Rust with C++ Codebases: `cxx`, `bindgen`, `extern "C"` Facades, and Exception Boundaries

A practical two-hour session on Rust with C++ Codebases, focused on cxx, bindgen, extern "C" Facades, and Exception Boundaries. The session treats Rust as a native component exposed through C-compatible boundaries, with attention to packaging, ownership, host-runtime tests, and failure handling.

Audience: entry-level and intermediate developers who want a practical engineering session, not a language tour.

Outcomes:

• Explain the practical boundaries of Rust with C++ Codebases
• Apply cxx in a small working example
• Apply bindgen in a small working example
• Apply extern "C" Facades in a small working example

Format: two hours with a short framing walkthrough, a concrete example, discussion of tradeoffs, and a closing checklist for practice.
