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::

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.
