friend constexpr auto iter_move( const iterator& i ) noexcept(/* see below */); | (since C++23) |
Equivalent to: return /*tuple-transform*/(ranges::iter_move, i.current_);
, where current_
denotes the underlying tuple-like object that holds iterators to elements of adapted views.
This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when zip_view::iterator<Const>
is an associated class of the arguments.
i | - | iterator |
std::move(*i)
if *i
is an lvalue reference, otherwise *i
.
