STD::ALLOCATOR(3cxx)

std::allocator< _Tp > 💖 — bestie page from the cxx manual ✨

okay so bestie, this is the page for std::allocator< _Tp >, and it lives in the cxx manual. It's giving "standard allocator, C++03 era, but make it iconic." Let's get into it. 💅

💖 NAME 💖

std::allocator< _Tp > — The standard allocator, as per C++03 [20.4.1]. 🎀

✨ SYNOPSIS ✨

#include <memory>

It inherits std::__new_allocator< _Tp >. slay. 🦋

🌸 Public Types 🌸

• typedef ptrdiff_t difference_type — the difference type, lowkey doing its typedef thing. 💜
• using is_always_equal = true_type — always equal? the type says true_type, periodt. ✨
• using propagate_on_container_move_assignment = true_type — propagates on container move assignment, and it's set to true_type. 💫
• typedef size_t size_type — size type, it's a size_t. 📏
• typedef _Tp value_type — value type is literally _Tp. 👑

💅 Public Member Functions 💅

• constexpr allocator (const allocator &__a) noexcept — copy constructor, constexpr and noexcept, no drama. 🫶
• template<typename _Tp1 > constexpr allocator (const allocator< _Tp1 > &) noexcept — templated converting constructor, also constexpr and noexcept. 🧚
• constexpr _Tp * allocate (size_t __n) — allocate! takes size_t __n, returns _Tp *, and it's constexpr. 🔥
• _Tp * allocate (size_type __n, const void *=static_cast< const void * >(0)) — the second allocate, with size_type __n and the exact const void *=static_cast< const void * >(0) bit. yes bestie, copy it exactly. 😭
• constexpr void deallocate (_Tp *__p, size_t __n) — deallocate, takes _Tp *__p and size_t __n, returns void, constexpr. 💀
• allocator & operator= (const allocator &)=default — copy assignment, defaulted. no cap. 💖

🫶 Friends 🫶

• constexpr bool operator== (const allocator &, const allocator &) noexcept — equality operator for two allocators, constexpr, noexcept. 🍓

🔗 Related Symbols 🔗

(Note that these are not member symbols.)

• template<typename _T1 , typename _T2 > constexpr bool operator== (const allocator< _T1 > &, const allocator< _T2 > &) noexcept — the cross-type equality operator, constexpr and noexcept, not a member. iykyk. 🌈

🦋 Detailed Description 🦋

template<typename _Tp>
class std::allocator< _Tp >"The standard allocator, as per C++03 [20.4.1].

Wait, that quote mark after std::allocator< _Tp > is in the source, bestie. We're not fixing it, we're just reporting it. 💅

It's the standard allocator, as per C++03 [20.4.1]. See https://gcc.gnu.org/onlinedocs/libstdc++/manual/memory.html#std.util.memory.allocator for further details. 🔥

🎀 Template Parameters 🎀

• _Tp — Type of allocated object. that's the whole vibe. 👑

💖 cute sign-off: source/version is libstdc++, page is std::allocator< _Tp >(3cxx). The footer didn't print a date, so we're not inventing one — it's timeless, periodt. 🫶✨
