Rust Memory Safety Examples v2.0

Comprehensive educational examples demonstrating memory-safe programming patterns in Rust for financial systems, critical infrastructure, and security-sensitive applications.

Purpose

This library provides clear, documented examples of how Rust’s ownership system prevents common memory safety vulnerabilities that affect C/C++ systems. Version 2.0 adds CVE case studies, secure programming patterns, and performance benchmarks.

What’s New in v2.0

• CVE Case Studies: Real-world vulnerability analysis (Heartbleed, Baron Samedit, etc.)
• Secure Patterns: Type-state, capability-based security, secret wrappers
• Performance Benchmarks: Measure safety overhead with criterion benchmarks
• Enhanced Documentation: Comprehensive explanations with industry references

Comparative Examples

Each module includes:

• Vulnerable C/C++ code patterns (commented examples)
• Safe Rust equivalents
• Explanations of how Rust prevents the vulnerability
• Real-world CVE references

Running Examples

# Run CVE case studies
cargo run --example cve_case_studies

# Run secure patterns demonstration
cargo run --example secure_patterns

# Run benchmarks
cargo bench

Alignment with Federal Guidance

These examples align with 2024-2025 CISA/FBI/NSA guidance recommending memory-safe languages for critical infrastructure to eliminate 70% of security vulnerabilities.
