#include <userver/formats/common/transfer_tag.hpp>
This tag class is used to move a ValueBuilder object without copying.
Unlike the move-constructor, if the object points to a subtree, only the pointer is copied. Note that storing the resulting ValueBuilder in a container for a long period of time will cause a "memory leak": the child ValueBuilder will hold the entire original tree, starting from the root.
