Memory Safety Patterns
Implement memory-safe programming with RAII, ownership, smart pointers, and resource…
A cross-language guide to memory-safe programming with RAII, ownership, smart pointers, and resource management across Rust, C++, and C. It maps every memory bug category to a concrete prevention pattern and shows the exact idioms that stop use-after-free, leaks, double-frees, and data races.

See the actual work before you buy it.
Memory bugs come in known classes, and each class has a known prevention; the work is mapping your codebase to the right ones. RAII in C++, ownership in Rust, goto-cleanup discipline in C, sanitizers in CI.
- Places the codebase on the safety spectrum first (manual C, smart pointer C++, ownership Rust, GC languages) and maps each memory bug class to its prevention: use-after-free to ownership/RAII, double-free to smart pointers, leaks to scope-tied lifetime, races to ownership plus sync.
- In C++ it enforces RAII end to end: resources tied to object lifetime with deleted copy constructors against double-close, lock_guard for mutexes, and a transaction wrapper that rolls back automatically unless commit is called.
- On the pointer layer it picks ownership deliberately: unique_ptr by default with std::move for transfer, shared_ptr only where sharing is real, weak_ptr to break reference cycles, make_shared/make_unique for exception safety.
- In Rust it leans on the compiler as layer one: move semantics, the one-mutable-or-many-immutable borrow rule, lifetimes on structs holding references, Cell/RefCell for narrow interior mutability and Rc/Arc plus Mutex/RwLock for shared state.
- In plain C it substitutes discipline for missing RAII: the goto-cleanup pattern so every error path releases resources, opaque create/destroy pairs that document ownership at the API line, and NULL-safe idempotent destroy against double-free.
- Closes with the tool layer in CI: bounds-checked access (vec.at(), Rust get()), AddressSanitizer and Valgrind for memory errors, ThreadSanitizer for races, Miri for undefined behavior, because no single layer is trusted alone.

-
I only write C++. Is the Rust and C material dead weight for me?
The C++ track stands on its own: RAII patterns for file handles, lock guards, and transaction rollback, plus smart-pointer idioms with custom deleters. The cross-language mapping mostly helps when you need to justify a language choice for a new component.
-
How does it prevent use-after-free instead of just describing it?
Every bug category maps to a concrete prevention pattern in a reference table covering six bug types, with the exact idiom that blocks it. A sanitizer tooling reference backs the patterns so you can verify at runtime, not just by review.
-
Will it make my existing codebase memory-safe on its own?
No. These are patterns and idioms you apply by hand while writing and refactoring. There is no automatic rewriting, and legacy code stays unsafe until you work through it.
