Rust Postgres Services: Transactions, Connection Pools, and Query Plans

A practical two-hour session on Rust Postgres Services, focused on Transactions, Connection Pools, and Query Plans. 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 Postgres Services
• Apply Transactions in a small working example
• Apply Connection Pools in a small working example
• Apply and Query Plans 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.
