std::ranges::enumerate_view<V>:: iterator

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

The return type of enumerate_view::begin , and of enumerate_view::end when the underlying view V is a common_range .

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

Member types

Member type	Definition
Base (private)	const V if Const is true , 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* )

Data members

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

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)

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)
