Rust Native Gems for Ruby: FFI, C Extensions, Memory Ownership, and Release Packaging

A practical two-hour session on Rust Native Gems for Ruby, focused on FFI, C Extensions, Memory Ownership, and Release Packaging. 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 Native Gems for Ruby
• Apply FFI in a small working example
• Apply C Extensions in a small working example
• Apply Memory Ownership 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.
