__GNU_CXX::_CASTER(3cxx)

✨ NAME ✨

okay so bestie, meet __gnu_cxx::_Caster< _ToType > πŸ’… this is from the 3cxx manual, and it’s a template struct that’s here to make pointer casting behave for containers. No cap.

🌈 SYNOPSIS 🌈

#include <cast.h>

πŸ’– Public Types πŸ’–

  • typedef _ToType::element_type * type β€” the one public type; literally a _ToType::element_type *.

πŸ¦‹ Detailed Description πŸ¦‹

template<typename _ToType>
    struct __gnu_cxx::_Caster< _ToType >

the original has a stray " glued right before β€œThese functions,” so consider that your daily dose of Doxygen chaos πŸ’€

okay so here’s the tea: these functions are here to allow containers to support non standard pointer types πŸ‘‘. For normal pointers, these resolve to the use of the standard cast operation. For other types, the functions will perform the appropriate cast to/from the custom pointer class β€” so long as that class meets these three conditions:

  1. it has a typedef element_type which names tehe type it points to β€” yes, tehe is in the original, not me, I would never 😭
  2. it has a get() const method which returns element_type*
  3. it has a constructor which can take one element_type* argument

and this type supports the semantics of the pointer cast operators (below.) β€” the docs say β€œbelow,” bestie. iykyk 🫢

ngl this whole thing is giving β€œtiny template, big container energy.” the vibes are immaculate, the requirements are specific, periodt. ✨

πŸŽ€ that’s the whole page, bestie β€” source/version: libstdc++, manual: 3cxx; the footer doesn’t give a date, so I’m not inventing one πŸ’€. Doxygen made this, and we’re obsessed. πŸ’–
