std::front_...ert_iterator(3)

🎀 NAME 🎀

std::front_insert_iterator::front_insert_iterator — that's the whole name, bestie, no cap. This is the std::front_...ert_iterator(3) page from the C++ Standard Libary (yes, the header spells it like that, and we're keeping it 💅). It's all about the constructor for std::front_insert_iterator, and it's lowkey iconic.

✨ Synopsis ✨

explicit front_insert_iterator( Container& c );            (until C++20)
constexpr explicit front_insert_iterator( Container& c );  (since C++20)

Initializes the underlying pointer to the container to std::addressof(c). That's the whole move. ✨

🌸 Parameters 🌸

• c — container to initialize the inserter with.

🦋 Defect reports 🦋

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

• DR: P2325R3
  • Applied to: C++20 — and yes, the source row also has a second C++20 floating around in it, so here's that too: C++20. Formatting chaos, but the facts stay. 💀
  • Behavior as published: default constructor was provided as requirement iterators must be default_initializable
  • Correct behavior: removed along with the requirement
