STD::_LIST_CONST_ITERATOR(3cxx)

🦋 std::_List_const_iterator< _Tp > (3cxx) — the const_iterator for list, bestie ✨

okay so real talk, this is the std::_List_const_iterator< _Tp > manpage from the libstdc++ docs — it lives in the 3cxx manual section, and we're about to get so educated 💅

---

🌸 NAME 🌸

std::_List_const_iterator< _Tp > — literally a list::const_iterator. that's it, that's the vibe 🎀

---

✨ SYNOPSIS ✨

#include <list>

🌈 Public Types 🌈

• _Node — typedef const _List_node< _Tp > — the node type, but make it const 👑
• _Self — typedef _List_const_iterator< _Tp > — bestie referring to herself, main character energy fr
• difference_type — typedef ptrdiff_t — the type you get when you subtract iterators
• iterator — typedef _List_iterator< _Tp > — the non-const sibling 🫶
• iterator_category — typedef std::bidirectional_iterator_tag — she walks both ways, no cap 🚶‍♀️
• pointer — typedef const _Tp * — pointer to const _Tp
• reference — typedef const _Tp & — reference to const _Tp
• value_type — typedef _Tp — the actual element type, iconic

💖 Public Member Functions 💖

• _List_const_iterator (const __detail::_List_node_base *__x) noexcept — build one from a node base pointer
• _List_const_iterator (const iterator &__x) noexcept — build one from a regular iterator, glow-up conversion ✨
• iterator _M_const_cast () const noexcept — const-casts back to a plain iterator
• reference operator* () const noexcept — dereference, aka get the actual element
• _Self & operator++ () noexcept — pre-increment, move forward one 🦋
• _Self operator++ (int) noexcept — post-increment, moves forward but hands you the old one
• _Self & operator-- () noexcept — pre-decrement, back it up
• _Self operator-- (int) noexcept — post-decrement, backwards but returns the pre-move copy
• pointer operator-> () const noexcept — member access through the iterator, lowkey essential

🍓 Public Attributes 🍓

• const __detail::_List_node_base * _M_node — the raw node pointer she's holding onto, the whole personality tbh

🧚 Friends 🧚

• bool operator== (const _Self &__x, const _Self &__y) noexcept — the equality check, because comparing iterators is a love language 💜

🔥 Detailed Description 🔥

template<typename _Tp>
    struct std::_List_const_iterator< _Tp >

"A list::const_iterator." — direct quote, she said it herself 💅

and the tea: all the functions are op overloads — like, every single one. operator this, operator that. operator overloads ate and left no crumbs 👑

okay that's the whole page bestie, go forth and iterate 💖

sign-off szn: this lil beauty comes from libstdc++ (libstdc++ is the source/version tag on the footer, fr fr), and the footer line reads libstdstd::_List_const_iterator< _Tp >(3cxx) — yes the man page footer is a little cursed, we don't talk about it 🙈 🎀
