Two objects of concurrent_unordered_set are equal if the following conditions are true:
- They contain an equal number of elements.
- Each element from one container is also available in the other.
template <typename T, typename Hash,
typename KeyEqual, typename Allocator>
bool operator==( const concurrent_unordered_set<T, Hash, KeyEqual, Allocator>& lhs,
const concurrent_unordered_set<T, Hash, KeyEqual, Allocator>& rhs );Returns: true if lhs is equal to rhs, false otherwise.
template <typename T, typename Hash,
typename KeyEqual, typename Allocator>
bool operator!=( const concurrent_unordered_set<T, Hash, KeyEqual, Allocator>& lhs,
const concurrent_unordered_set<T, Hash, KeyEqual, Allocator>& rhs );Equivalent to !(lhs == rhs).
Returns: true if lhs is not equal to rhs; false, otherwise.
