Rust Developer Tooling: rustfmt, clippy, cargo-nextest, and Review Signals

A practical two-hour session on Rust Developer Tooling, focused on rustfmt, clippy, cargo-nextest, and Review Signals. 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 Developer Tooling
• Apply rustfmt in a small working example
• Apply clippy in a small working example
• Apply cargo-nextest 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.
