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