Rust Error Handling in Applications: anyhow, thiserror, Context, and Boundaries

A practical two-hour session on Rust Error Handling in Applications, focused on anyhow, thiserror, Context, and Boundaries. 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 Error Handling in Applications
• Apply anyhow in a small working example
• Apply thiserror in a small working example
• Apply Context 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.
