Rust Plugin Systems for Existing Apps: C ABI VTables, Capability Checks, and Version Negotiation

A practical two-hour session on Rust Plugin Systems for Existing Apps, focused on C ABI VTables, Capability Checks, and Version Negotiation. 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 Plugin Systems for Existing Apps
• Apply C ABI VTables in a small working example
• Apply Capability Checks in a small working example
• Apply and Version Negotiation 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.
