friend
constexpr
void iter_swap(
const
/*iterator*/
& x, const
/*iterator*/
& y )
noexcept
(
/* see description */
)
|
(since C++23) | |
Applies
ranges::iter_swap
to the stored underlying iterators. Formally, for every integer 0 ≤ i ≤ sizeof...(Vs), performs
ranges::iter_swap
(std::
get
<i>
(x.current_
), std::
get
<i>
(y.current_
)
)
, where current_
This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when cartesian_product_view::iterator<Const>
Parameters
| x, y | - | iterators to the elements to swap |
Return value
(none)
Exceptions
The exception specification is equivalent to the logical AND of the expression noexcept ( ranges::iter_swap (std:: get <i> (x.current_ ), std:: get <i> (y.current_ ) ) ) for every integer 0 ≤ i ≤ sizeof...(Vs)
