std::ranges::enumerate_view<V>::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 functions
|
(C++23)
|
constructs an iterator (public member function) |
|
(C++23)
|
returns an iterator to current element (public member function) |
|
(C++23)
|
returns current index (public member function) |
|
(C++23)
|
accesses the element (public member function) |
|
(C++23)
|
accesses an element by index (public member function) |
|
(C++23)
|
advances or decrements the underlying iterator (public member function) |
Non-member functions
|
(C++23)
|
compares the underlying iterators (function) |
|
(C++23)
|
performs iterator arithmetic (function) |
|
(C++23)
|
casts the result of dereferencing the underlying iterator to its associated rvalue reference type (function) |
