Move operations take source’s value, but leave source in valid state: class Widget {public: Widget(Widget&& rhs): pds(rhs.pds) // take source’s value { rhs.pds = nullptr; } // leave source in valid state Widget& operator=(Widget&& rhs) {delete pds; // get rid of current value 2021-04-07 · std::move is used to indicate that an object t may be "moved from", i.e. allowing the efficient transfer of resources from t to another object. In particular, std::move produces an xvalue expression that identifies its argument t.

Move Semantics. Let’s say there is a big object and its data is being transferred to another object of the same type. In C++ and many other programming languages, this could be accomplished with
