Rust FFI Testing Strategy: ABI Fixtures, Sanitizers, Host Runtime Tests, and Crash Reproduction

A practical two-hour session on Rust FFI Testing Strategy, focused on ABI Fixtures, Sanitizers, Host Runtime Tests, and Crash Reproduction. 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 FFI Testing Strategy
• Apply ABI Fixtures in a small working example
• Apply Sanitizers in a small working example
• Apply Host Runtime Tests 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.
