Rust Webhooks with Axum: Signatures, Idempotency, and Retry Safety

A practical two-hour session on Rust Webhooks with Axum, focused on Signatures, Idempotency, and Retry Safety. 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 Webhooks with Axum
• Apply Signatures in a small working example
• Apply Idempotency in a small working example
• Apply and Retry Safety 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.
