"Isn’t that what is in the example?" No. Your example has one level of indirection less. Anyway, don't do that. Just make BaseStruct abstract. That's all you need.

Isn’t that what is in the example? Struct derivedStruct : public BaseStruct

No, you need a new base class for the data to derive from. So you have struct StructA : BaseData {...} etc.

Since there are multiple "derived" structs, would the member for the BaseStruct that points to the "derived" struct has to be a template since the BaseStruct has to be able to point to different structs i.e BaseStruct -> StructA, BaseStruct -> StructB ?
