Rust Command-Line Data Apps: Input Files, Progress, Errors, and Outputs

A practical two-hour session on Rust Command-Line Data Apps, focused on Input Files, Progress, Errors, and Outputs. 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 Command-Line Data Apps
• Apply Input Files in a small working example
• Apply Progress in a small working example
• Apply Errors 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.
