Size is next polymorphism my main reason why I would use a class
instead of a struct.
A good heuristic size (which I have heard here) was: <= 16 bytes
-> struct, > 16 bytes -> class.
And what are your reasons for decision?
And I believe, actually, that passing a massive struct by value
if it's an rvalue IS the most performant -- no copy needed, no
referencing needed.
And what a massive struct do you think?
For example, if you have something like this:
struct Massy {
public:
int[1024] marr;
}
I would bet that it is usually better to take 'Massy' by ref, or
to use a class, instead of a move or a copy.
