std::ranges...face::cbegin(3)

💖 std::ranges::view_interface::cbegin — C++ Standard Library, bestie

🌸 NAME

std::ranges::view_interface::cbegin — that's the name, no cap. It's giving "tiny but important member function" energy.

---

📜 Synopsis

The default implementation of cbegin() member function returns a constant beginning iterator of the range. There's literally a diagram for this vibe: range-begin-end.svg

constexpr auto cbegin();                                       (1)
(since C++23)
constexpr auto cbegin() const requires ranges::range<const D>; (2)
(since C++23)

1. Let derived be a reference bound to static_cast<D&>(*this). Equivalent to return ranges::cbegin(derived);.
2. Same as (1), except that derived is static_cast<const D&>(*this).

🎀 Parameters

(none) — literally none, bestie. Not a single parameter. She's low-maintenance like that.

---

✨ Return value

A constant beginning iterator of the range.

---

💅 Notes

All range adaptors and range factories in the standard library and std::ranges::subrange use the default implementation of cbegin. So yeah, this default implementation is doing a LOT of heavy lifting behind the scenes. Iconic behavior, honestly.
