Rust Error Contracts Across FFI: Status Codes, Out Parameters, Strings, and Unwind Containment

A practical two-hour session on Rust Error Contracts Across FFI, focused on Status Codes, Out Parameters, Strings, and Unwind Containment. 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 Error Contracts Across FFI
• Apply Status Codes in a small working example
• Apply Out Parameters in a small working example
• Apply Strings 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.
