November 9, 2025November 1, 2025 by Garry Chen 101

Data Structures with Smart Pointers in Rust

Deep dive into Rust smart pointers covering Box for heap memory allocation, Cow<'a, B> for copy-on-write optimization, and MutexGuard for thread-safe resource management. Learn how smart pointers implement Deref, DerefMut, and Drop traits to provide automatic memory management and resource cleanup. Includes practical examples of custom allocators, URL parsing optimization, and building your own MyString smart pointer for efficient small string storage.
