Defined in header <forward_list>

std::forward_list is a container that supports fast insertion and removal of elements from anywhere in the container. Fast random access is not supported. It is implemented as singly-linked list and essentially does not have any overhead compared to its implementation in C. Compared to std::list this container provides more space efficient storage when bidirectional iteration is not needed.

std::forward_list meets the requirements of Template:concept (except for the size() member function), Template:concept and Template:concept.
