Returns an
iterator
or a
sentinel
that compares equal to the end iterator of the
enumerate_view
.
Let
base_
denote the underlying view.
1)
Equivalent to:
if constexpr (ranges::forward_range<V> and ranges::common_range<V> and ranges::sized_range<V>) return /*iterator*/<false>(ranges::end(base_), ranges::distance(base_)); else return /*sentinel*/<false>(ranges::end(base_));
2)
Equivalent to:
if constexpr (ranges::forward_range<const V> and ranges::common_range<const V> and ranges::sized_range<const V>) return /*iterator*/<true>(ranges::end(base_), ranges::distance(base_)); else return /*sentinel*/<true>(ranges::end(base_));

Parameters
