std::ranges::zip_transform_view<F,Views...>::end

constexpr auto end();
 (1) (since C++23) 
constexpr auto end() const
    requires ranges::range<const /*InnerView*/> &&
             std::regular_invocable<const F&,
                 ranges::range_reference_t<const Views>...>;
 (2) (since C++23)

Returns an iterator or a sentinel that compares equal to the end iterator of the zip_transform_view.

Let zip_ denote the underlying tuple of views:

1) Equivalent to:
if constexpr (ranges::common_range</*InnerView*/>)

return /*iterator*/<false>(*this, zip_.end());
else
.

return /*sentinel*/<false>(zip_.end());
2) Equivalent to:
if constexpr (ranges::common_range<const /*InnerView*/>)

return /*iterator*/<true>(*this, zip_.end());
else
.

return /*sentinel*/<true>(zip_.end());

Parameters

(none).

Return value

An iterator or sentinel representing the end of the zip_transform_view, as described above.
