Are C++ recursive type definitions possible, in particular can I put a vector within the definition of T?

Question

For one of my projects, what I really wanted to do was this (simplifying it to the bare minimum);

struct Move
{
    int src;
    int dst;
};

struct MoveTree         


        

Answer 1

Use a pointer to the type in the Vector, this will be portable.

struct Move
    {
        int src;
        int dst;
    };

struct MoveTree;

struct MoveTree
    {
        Move move;
        std::vector variation;
    };
