class tsl::detail_robin_hash::robin_hash< ValueType, KeySelect, ValueSelect, Hash, KeyEqual, Allocator, StoreHash, GrowthPolicy >
Internal common class used by robin_map and robin_set.
ValueType is what will be stored by robin_hash (usually std::pair<Key, T> for map and Key for set).
KeySelect should be a FunctionObject which takes a ValueType in parameter and returns a reference to the key.
ValueSelect should be a FunctionObject which takes a ValueType in parameter and returns a reference to the value. ValueSelect should be void if there is no value (in a set for example).
The strong exception guarantee only holds if the expression std::is_nothrow_swappable<ValueType>::value && std::is_nothrow_move_constructible<ValueType>::value is true.
Behaviour is undefined if the destructor of ValueType throws.

C++11 doesn't support the creation of a std::vector with a custom allocator and 'count' default-inserted elements. The needed contructor explicit vector(size_type count, const Allocator& alloc = Allocator()); is only available in C++14 and later. We thus must resize after using the vector(const Allocator& alloc) constructor.
We can't use vector(size_type count, const T& value, const Allocator& alloc) as it requires the value T to be copyable.
template<class ValueType, class KeySelect, class ValueSelect, class Hash, class KeyEqual, class Allocator, bool StoreHash, class GrowthPolicy>
Here to avoid template<class K> size_type erase(const K& key) being used when we use an iterator instead of a const_iterator.
Erase bucket used a backward shift after clearing the bucket. Check if there is a new value in the bucket, if not get the next non-empty.
