std::ranges::enumerate_view
(C++26)
iter_move(enumerate_view::iterator)
friend constexpr auto iter_move( const /*iterator*/& i ) noexcept(/* see below */)
(since C++23)
Let current_ be the underlying iterator, pos_ be the underlying index, and Base be the (possibly cv-qualified) type of the underlying sequence.
Equivalent to:
template<class D, class B> using tuple = std::tuple <D, ranges::range_rvalue_reference_t <B>>; return tuple<difference_type, Base>(i.pos_, ranges::iter_move (i.current_));
This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when enumerate_view::iterator<Const> is an associated class of the arguments.
