• 🗑️ Automatically remove fulfilled orders using HashMap retention
• 🔄 Persistent order management with thread-safe global state
• 🎯 Clean CLI interface with input validation

Tech Stack

• Language: Rust
• Data Structure: HashMap for efficient order lookup
• Concurrency: Arc<Mutex<>> for thread-safe operations
• Dependencies: once_cell for lazy static initialization

Architecture

• Modular design with separate utils module
• Global static OrderTracker with proper error handling
• Clean separation of concerns between lib.rs, main.rs, and utils.rs

Perfect for learning Rust ownership, error handling, and CLI application development!
