friend constexpr decltype(auto)     iter_move( const /*iterator*/& it ) noexcept(/* see description */);		(since C++26)

Returns the result of applying ranges::iter_move to the underlying iterator contained in it_ .

Let Ref be concat-rvalue-reference-t <maybe-const <Const, Views>...>. Equivalent to return std::visit([](const auto& i) -> Ref { return ranges::iter_move(i); }, it.it_ );.

If it.it_.valueless_by_exception() is true, the behavior is undefined.

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when concat_view::iterator <Const> is an associated class of the arguments.

Parameters

it

-

iterator

Return value

The result of applying ranges::iter_move to the underlying iterator.
