NAME¶

std::ranges::enumerate_view::iterator - std::ranges::enumerate_view::iterator

Synopsis¶

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

(exposition-only member object*)
pos_ (private) A current index of type difference_type

Member functions¶

constructor constructs an iterator
(C++23) (public member function)
base returns an iterator to current element
(C++23) (public member function)
index returns current index
(C++23) (public member function)
operator* accesses the element
(C++23) (public member function)
operator[] accesses an element by index
(C++23) (public member function)
operator++
operator++(int)
operator-- advances or decrements the underlying iterator
operator--(int) (public member function)
operator+=
operator-=
(C++23)

Non-member functions¶

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