Rust CLI Development

Overview

Rust provides excellent tools for building high-performance command-line applications. This skill should be invoked when creating CLI tools that require performance, safety, or native binaries.

Core Principles

• Clap: Use clap for argument parsing
• Error Handling: Use Result and the ? operator
• Structopt: Derive CLI from structs
• Binary Focus: Focus on single-purpose tools

Preparation Checklist

• Initialize: cargo new --bin <name>
• Add clap: cargo add clap
• Plan CLI structure
• Design error handling
