2 things to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

What its author says it does
Copied from the file, not written here
Implement memory-safe programming with RAII, ownership, smart pointers, and resource management across Rust, C++, and C. Use when writing safe systems code, managing resources, or preventing memory bugs.

Memory Safety Patterns
Cross-language patterns for memory-safe programming including RAII, ownership, smart pointers, and resource management.
When to Use This Skill
- Writing memory-safe systems code
- Managing resources (files, sockets, memory)
- Preventing use-after-free and leaks
- Implementing RAII patterns
- Choosing between languages for safety
- Debugging memory issues
Core Concepts
1. Memory Bug Categories
| Bug Type | Description | Prevention |
|---|---|---|
| Use-after-free | Access freed memory | Ownership, RAII |
| Double-free | Free same memory twice | Smart pointers |
| Memory leak | Never free memory | RAII, GC |
| Buffer overflow | Write past buffer end | Bounds checking |
| Dangling pointer | Pointer to freed memory | Lifetime tracking |
| Data race | Concurrent unsynchronized access | Ownership, Sync |
2. Safety Spectrum
Manual (C) → Smart Pointers (C++) → Ownership (Rust) → GC (Go, Java)
Less safe More safe
More control Less control

Best Practices
Do's
- Prefer RAII - Tie resource lifetime to scope
- Use smart pointers - Avoid raw pointers in C++
- Understand ownership - Know who owns what
- Check bounds - Use safe access methods
- Use tools - AddressSanitizer, Valgrind, Miri
Don'ts
- Don't use raw pointers - Unless interfacing with C
- Don't return local references - Dangling pointer
- Don't ignore compiler warnings - They catch bugs
- Don't use
unsafecarelessly - In Rust, minimize it - Don't assume thread safety - Be explicit
Debugging Tools
# AddressSanitizer (Clang/GCC)
clang++ -fsanitize=address -g source.cpp
# Valgrind
valgrind --leak-check=full ./program
# Rust Miri (undefined behavior detector)
cargo +nightly miri run
# ThreadSanitizer
clang++ -fsanitize=thread -g source.cpp
