Defined in header <unordered_set>
template<

    class Key,
    class Hash = std::hash<Key>,
    class KeyEqual = std::equal_to<Key>,
    class Allocator = std::allocator<Key>

> class unordered_set;
(since C++11)

Unordered set is an associative container that contains set of unique objects of type Key. Search, insertion, and removal have average constant-time complexity.

std::unordered_set meets the requirements of Container, AllocatorAwareContainer, UnorderedAssociativeContainer.
