Introduction - The Little Book of Rust Macros

Comprehensive guide to understanding and writing Rust macros:

What It Covers:

• Macro Fundamentals: How macros work in Rust’s compilation process
• Declarative Macros: macro_rules! patterns and syntax
• Procedural Macros: Custom derive, attribute, and function-like macros
• Advanced Patterns: Complex macro techniques and best practices
• Debugging: Tools and techniques for debugging macro code

Why Macros Matter in Rust:

• Code Generation: Eliminate boilerplate and repetitive code
• Domain-Specific Languages: Create custom syntax for specific use cases
• Compile-Time Logic: Perform complex operations at compile time
• Zero-Cost Abstractions: Generate efficient code without runtime overhead

Learning Path:

1. Start with simple macro_rules! examples
2. Understand pattern matching in macros
3. Progress to procedural macros
4. Learn debugging and testing techniques

The Rust Performance Book

Title Page - The Rust Performance Book

Authoritative guide to optimizing Rust code performance by Nicholas Nethercote:

Key Topics:

• Profiling: Tools and techniques for measuring performance
• Memory Management: Optimizing allocations and memory usage
