Detailed Description

template<class ValueType, class KeySelect, class ValueSelect, class Hash, class KeyEqual, class Allocator, bool StoreHash, class GrowthPolicy>
template<bool IsConst>
class tsl::detail_robin_hash::robin_hash< ValueType, KeySelect, ValueSelect, Hash, KeyEqual, Allocator, StoreHash, GrowthPolicy >::robin_iterator< IsConst >

The 'operator*()' and 'operator->()' methods return a const reference and const pointer respectively to the stored value type.

In case of a map, to get a mutable reference to the value associated to a key (the '.second' in the stored pair), you have to call 'value()'.

The main reason for this is that if we returned a std::pair<Key, T>& instead of a const std::pair<Key, T>&, the user may modify the key which will put the map in a undefined state.
