Recipes

Self-contained, copy-pasteable solutions to whole problems. Each recipe is a complete program you can drop into src/main.rs and adapt.

• A 12-Factor Service — env-first config with a file fallback
• A git-like Multi-Tool — nested subcommands with their own flags
• A Deploy CLI — config file + per-environment overrides
• Testing figue Parsers — from_slice, MockEnv, inline file content
