Rust for Non-Systems Programmers
summary
Builds a small CLI that fetches OpenWeather, deserializes JSON into structs, compares today and yesterday, and prints a receipt style summary that actually prints to a thermal printer and shows a smiley for 60–80°F. Uses structopt for CLI, serde for parsing, reqwest for HTTP and the error crate for wrapped diagnostics. Naive implementation runs ~0.1s, tests exercise temp-delta logic, cloning is suggested as a practical workaround for reference headaches.
