A practical two-hour session on Rust gRPC Services with tonic, focused on Protobuf, Streaming, and Error Contracts. 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 gRPC Services with tonic
• Apply Protobuf in a small working example
• Apply Streaming in a small working example
• Apply and Error Contracts 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.
