STD::DEFAULT_DELETE(3cxx)

💖 std::default_delete< _Tp > 💖

okay so bestie, welcome to the std::default_delete< _Tp > page — this is the libstdc++ manpage for it, and we're gonna get you comfy with it, no cap 🫶

---

✨ SYNOPSIS ✨

First things first, you gotta pull it in:

#include <memory>

🎀 Public Member Functions

• constexpr default_delete () noexcept=default — the default constructor. yes queen, it's just sitting there being defaulted ✨ (described below as "Default constructor.")
• template<typename _Up , typename = _Require<is_convertible<_Up*, _Tp*>>> constexpr default_delete (const default_delete< _Up > &) noexcept — the converting constructor. it lets you convert from a deleter made for another type (_Up) but only if _Up* is convertible to _Tp* — the _Require is doing the gatekeeping 💅 (described below as "Converting constructor.")
• constexpr void operator() (_Tp *__ptr) const — calls delete __ptr, that's literally the whole job. iconic.

🌸 Detailed Description 🌸

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

it's giving "Primary template of default_delete, used by unique_ptr for single objects" 💀 like, this is the little guy that unique_ptr uses under the hood for single objects. main character energy fr fr 👑

⭐ Since

C++11

(the way this is old enough to be a classic but still slays 😭)

💜 Constructor & Destructor Documentation 💜

🦋 template<typename _Tp > constexpr std::default_delete< _Tp >::default_delete () [constexpr], [default], [noexcept]

Default constructor. that's it. that's the whole thing. it's constexpr, it's default, it's noexcept — a triple threat, we love to see it ✨

🦋 template<typename _Tp > template<typename _Up , typename = _Require<is_convertible<_Up*, _Tp*>>> constexpr std::default_delete< _Tp >::default_delete (const default_delete< _Up > &) [inline], [constexpr], [noexcept]

Converting constructor. bestie read carefully: it "Allows conversion from a deleter for objects of another type, _Up, only if _Up* is convertible to _Tp*." so like, it's not free-for-all conversion, the types gotta actually be compatible or it just won't let you in 🙈 note the [inline], [constexpr] and [noexcept] — yes all three, she's versatile 🎀

🔥 Member Function Documentation 🔥

🌈 template<typename _Tp > constexpr void std::default_delete< _Tp >::operator() (_Tp * __ptr) const [inline], [constexpr]

Calls delete __ptr

that's the vibe. you hand it __ptr, it deletes it. [inline] and [constexpr] on deck. periodt 💅

💖 that's the whole page bestie — no extra lore, no hidden flags, just the deleter doing its deleter thing. iykyk 🧚

and that's a wrap on this libstdc++ page for std::default_delete< _Tp >(3cxx) 🍓 thanks for reading babe, go delete some pointers (responsibly) 💜✨
