template<bool Const> class/iterator/		(since C++23) (exposition only*)

The return type ofenumerate_view::begin, and ofenumerate_view::end when the underlying viewV is acommon_range.

The type/*iterator*/<true> is returned by the const-qualified overloads. The type/*iterator*/<false> is returned by the non-const-qualified overloads.

[edit]Member types

Member type	Definition
`Base`(private)	const V if`Const` istrue, otherwise`V`. (exposition-only member type*)
`iterator_category`	std::input_iterator_tag
`iterator_concept`	std::random_access_iterator_tag, if`Base` models`random_access_range`. Otherwise, std::bidirectional_iterator_tag, if`Base` models`bidirectional_range`. Otherwise, std::forward_iterator_tag, if`Base` models`forward_range`. Otherwise, std::input_iterator_tag.
`difference_type`	ranges::range_difference_t<Base>
`value_type`	std::tuple<difference_type,ranges::range_value_t<Base>>
`reference-type`(private)	std::tuple<difference_type,ranges::range_reference_t<Base>> (exposition-only member type*)

[edit]Data members

Member name	Definition
`current_`(private)	An iterator to the current element of typeranges::iterator_t<Base> (exposition-only member object*)
`pos_`(private)	A current index of type`difference_type` (exposition-only member object*)

[edit]Member functions

(constructor)	constructs an iterator (public member function)
base	returns an iterator to current element (public member function)
index	returns current index (public member function)
operator*	accesses the element (public member function)
operator[]	accesses an element by index (public member function)
operator++operator++(int)operator--operator--(int)operator+=operator-=	advances or decrements the underlying iterator (public member function)[edit]

[edit]Non-member functions

operator==operator<=> (C++23)	compares the underlying iterators (function)
operator+operator- (C++23)	performs iterator arithmetic (function)
iter_move (C++23)	casts the result of dereferencing the underlying iterator to its associated rvalue reference type (function)
