In-Depth Exploration of Smart Pointers in Rust: Rc, Arc, and RefCell

Introduction In Rust, smart pointers are structures that encapsulate pointers, responsible for managing memory and automatically reclaiming resources. Rust’s memory management is centered around ownership, but in some cases, programmers may need more flexibility, especially when dealing with shared ownership and mutability. At this point, Rust offers several smart pointers, the most commonly used being … Read more

Understanding Rust's Smart Pointers: Box, Rc, and RefCell

Introduction In Rust, memory management is a very important task. Rust helps developers avoid many common memory issues through mechanisms such as ownership, borrowing, and lifetimes. However, Rust also provides some smart pointers for handling heap-allocated memory, which not only simplify memory management but also give us more flexibility. This article will detail several smart … Read more

The RAII Pattern in C++: The Golden Rule of Resource Management

In the world of C++ programming, resource management has always been a headache, especially when dealing with memory, file handles, and other system resources. Today, I want to explore a very important concept with you—RAII (Resource Acquisition Is Initialization). Through this article, you will understand how RAII helps us manage resources effectively, avoiding common memory … Read more

C++ std::shared_ptr and std::weak_ptr: The End of Circular References

In C++, forgetting to release dynamically allocated memory is a common pitfall for beginners. To address this issue, smart pointers have emerged. The smart pointer std::shared_ptr allows multiple pointers to share the same memory and manages its lifecycle through reference counting, which is very convenient. However, std::shared_ptr is not infallible; it has a fatal flaw: … Read more
