Key Points

• Memory Allocation: Structs are allocated on the stack (unless boxed). This makes them more efficient for small data structures.

• Immutability: While structs can have mutable fields, they are often used as immutable types. Immutable structs ensure that their data cannot be changed after they are created.

• Use Cases: Structs are best used for small, simple objects that have value semantics, such as coordinates, complex numbers, or RGB colors.
