What are some unique scenarios for using std::unique_ptr in C++?

std::unique_ptr is great for managing dynamic memory. One unique scenario is when implementing a resource manager that handles multiple resources.

Can you give me an example of that?

Sure! Imagine a game engine where you have various game objects. Using std::unique_ptr allows you to ensure that each object is properly deleted when no longer needed.

What about using it in a factory pattern?

Absolutely! In a factory pattern, you can return std::unique_ptr to ensure that the created objects are owned by the caller, preventing memory leaks.

Are there any performance benefits?

Yes, std::unique_ptr has low overhead compared to raw pointers and helps avoid memory fragmentation, leading to better performance.
