Rust Resource Management: Files, Sockets, Locks, and Cleanup

A practical two-hour session on Rust Resource Management, focused on Files, Sockets, Locks, and Cleanup. 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 Resource Management
• Apply Files in a small working example
• Apply Sockets in a small working example
• Apply Locks 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.
