std::ranges...view::begin(3)

🦋 std::ranges::join_with_view::begin 🦋

okay so bestie, this page is from the C++ Standard Libary manual, section 3, and the whole main-character moment is std::ranges::join_with_view::begin. no cap, that’s the exact page name. 💖

✨ NAME ✨

std::ranges::join_with_view::begin — std::ranges::join_with_view::begin

✨ Synopsis ✨

Overload (1):

constexpr auto begin();

(1) — since C++23.

Overload (2):

constexpr auto begin() const
  requires ranges::input_range<const V> &&
           ranges::forward_range<const Pattern> &&
           std::is_reference_v<ranges::range_reference_t<const V>>;

(2) — since C++23.

Returns an iterator to the first element of the join_with_view. 🫶

Let base_ denote the underlying view:

1. Equivalent to return /*iterator*/<true>{*this, ranges::begin(base_)}; if V and Pattern each model __SimpleView and ranges::range_reference_t<V> is a reference type; otherwise equivalent to return /*iterator*/<false>{*this, ranges::begin(base_)};.
2. Equivalent to return /*iterator*/<true>{*this, ranges::begin(base_)};.

✨ Parameters ✨

• (none) — literally no parameters, bestie. 💅

✨ Return value ✨

An iterator to the first element of the join_with_view, as described above. That’s the whole return-value vibe. 🌈
