auto-allocator 0.1.0

/// 🚀 Auto-Allocator Basic Usage Demo
///
/// This example demonstrates the core functionality of auto-allocator:
/// 1. 🎯 Zero-configuration automatic allocator selection
/// 2. 📊 System information viewing
/// 3. ⚙️ Environment variable control methods
/// 4. 🧪 Basic memory allocation testing

// This is the core usage of auto-allocator: just one use statement enables automatic allocator selection
#[allow(clippy::single_component_path_imports)]
