The companion code repository for the O'Reilly book 'Command-Line Rust' by Ken Youens-Clark, containing small complete Rust programs built chapter by chapter. It teaches Rust through writing, testing, and refining command-line tools using the clap argument parser.

Use cases

• learn rust by building command-line programs
• find example rust cli projects with tests
• understand how to parse command-line arguments with clap
• learn error handling and file io in rust
• see how to parse delimited and raw text in rust
• study a rust book's source code
• practice writing rust programs that fail gracefully

When to choose

• you are learning Rust and prefer a project-based, hands-on approach
• you want to build command-line tools in Rust with clap
• you want tested, complete example programs to study or adapt
• you need guidance on Rust error handling, file I/O, and argument validation

When to avoid

• you need a production-ready CLI framework or library rather than educational code
• you want comprehensive coverage of all of Rust, such as async, web, or systems programming topics
• you are not interested in command-line programming
