9 Iterators library [iterators]

9.7 Iterator adaptors [iterators.predef]

9.7.1 Reverse iterators [iterators.reverse]

9.7.1.2 reverse_iterator operations [reverse.iter.ops]

9.7.1.2.21 iter_move [reverse.iter.iter_move]

friend constexpr rvalue_reference_t<I> iter_move(const reverse_iterator& i) noexcept(see below);

1

Effects: Equivalent to: return ranges::iter_move(prev(i.current));

2

Remarks: The expression in noexcept is equivalent to: 

   noexcept(ranges::iter_move(declval<I&>())) && noexcept(--declval<I&>()) &&
     is_nothrow_copy_constructible<I>::value
