“moveable” basically means that you can just "move" memory when you want to shift data in memory. You do not need to call a constructor and a destructor in a row. Such a situation happens very often when you want to resize a vector, which stores data in a continuous piece of memory. You just need to move old data into a newly allocated memory. If your data is "moveable" you can just call the memcpy() function instead of calling a copy constructor in a loop.
Hope this helps.
