[Rust Guide] 4.1. Ownership - Stack Memory vs. Heap Memory

4.1.0 Before We Begin After learning Rust’s general programming concepts, you’ve arrived at the most important topic in all of Rust—ownership. It’s quite different from other languages, and many beginners find it hard to learn. This chapter aims to help beginners fully master this feature. This chapter has three sections: Ownership: Stack Memory vs. Heap Memory (this article) Ownership Rules, Memory, and Allocation Ownership and Functions If you find this helpful, please like, bookmark, and follow. To keep learning along, follow this series. 4.1.1 What Is Ownership? Ownership is Rust’s most unique feature. It allows Rust to guarantee memory safety without a GC (garbage collector). All programs must manage how they use computer memory while running. Some languages rely on garbage collection: while the program runs, they continuously look for memory that is no longer being used (for example, C#). In other languages, the programmer must explicitly allocate and free memory (for example, C/
