std::ranges::join_with_view
join_with_view::begin
constexpr auto begin();
(1)
(since C++23)
constexpr auto begin() const
(2)
(since C++23)
requires ranges::forward_range <const V> &&
ranges::forward_range <const Pattern> &&

Returns an iterator to the beginning of the join_with_view.
1) Returns a mutable iterator or const iterator.
- If
Vmodelsforward_range, equivalent to constexpr bool use_const =simple-view<V> && std::is_reference_v <InnerRng> &&simple-view<Pattern>;
returniterator<use_const>{*this, ranges::begin (base_)};. - Otherwise, equivalent to
outer_it_base_);
returniterator<false>{*this};.
2) Returns a const iterator.
For the definition of
concatable , see std::ranges::concat_view.[edit] Return value
1) As described above.
2)
iterator <true>{*this, ranges::begin (base_ )}.[edit] Example
