Understanding Memory Management in Rust

TLDRThis video explains memory management in Rust, covering stack vs heap allocation, struct allocation on the stack, and dynamic allocation on the heap using Box::new.

Key insights

💡Structs in Rust can be allocated on the stack or the heap.

🧱Stack allocation is used for structs defined locally within a function.

💻Heap allocation is used for structs created with Box::new.

Q&A

What is the difference between stack and heap allocation?

Stack allocation is fast but has limited size, while heap allocation allows dynamic memory allocation but is slower.

When should I use stack allocation?

Stack allocation is suitable for smaller data that is only needed within a function scope.

When should I use heap allocation?

Heap allocation is suitable for larger data or data that needs to be accessed outside of its original scope.
