A practical two-hour session on Rust API Error Handling with Axum, focused on Validation, Status Codes, and Typed Responses. Rust is used as the implementation context while the core lesson stays on software engineering fundamentals, reliability, testing, and operational clarity.

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

Outcomes:

• Explain the practical boundaries of Rust API Error Handling with Axum
• Apply Validation in a small working example
• Apply Status Codes in a small working example
• Apply and Typed Responses 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.
