Rust Programming 2023 - A Comprehensive Course for Beginners - What Are Smart Pointers in Rust

The video tutorial introduces pointers and smart pointers in Rust, explaining their roles in memory management. It covers the basic concept of pointers, the difference between regular and smart pointers, and the specific use of the Box smart pointer to manage heap memory. The tutorial includes a coding example demonstrating how to use Box for memory allocation and dereferencing. It concludes with a brief overview of traits and generic structures, setting the stage for creating custom smart pointers in future lessons.
