Rust Payment-Style Workflows: Idempotency, Audit Logs, and State Machines

A practical two-hour session on Rust Payment-Style Workflows, focused on Idempotency, Audit Logs, and State Machines. 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 Payment-Style Workflows
• Apply Idempotency in a small working example
• Apply Audit Logs in a small working example
• Apply and State Machines 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.
