memory-safety-patterns

Memory safety in C++ uses RAII to bind resource lifetimes to object scope, ensuring automatic cleanup and preventing leaks. Smart pointers manage dynamic memory automatically, eliminating manual deallocation errors and undefined behavior in systems programming.

Cross-language resource ownership applies language-agnostic patterns: RAII and smart pointers in C++, strict ownership in Rust, and disciplined manual resource handling in C. This ensures correct lifetime management and prevents undefined behavior across systems programming components.

Yes, these memory safety patterns apply directly to systems programming and performance-critical components. The techniques codify safe resource handling, file and socket management, and concurrency patterns without sacrificing the low-level control required for high-performance applications.

Rust ownership rules enforce strict compile-time lifetime and borrowing checks to prevent memory bugs. This guarantees every resource has a single owner, eliminating dangling pointers, data races, and double frees without runtime overhead in performance-critical code.

You should avoid smart pointers when managing non-memory resources or when interfacing with C APIs that expect raw pointers. In these cases, incorrect smart pointer usage can hide ownership bugs or cause cycles, so careful manual resource handling or custom deleters are required.
