STD::RANGES::VIEW_INTERFACE(3)

💖 std::ranges::view_interface< _Derived > 💖

okay so bestie, you've wandered into the Library Functions Manual section 3 — that's the C++ library calls zone, and today's main character is a class template. yes. a template. she's flexible like that. 🦋

---

✨ NAME ✨

std::ranges::view_interface< _Derived > — the ranges::view_interface class template. that's her. that's the whole name. slay.

---

🌸 SYNOPSIS 🌸

#include <ranges>

Inherited by , and .

not me reading "Inherited by , and ." and getting nothing 😭 like the list is literally empty, that's just how the page is generated, bestie. no names. no cap. moving on.

👑 Public Member Functions 👑

• constexpr decltype(auto) back () — grab the last element. non-const version, go off.
• constexpr decltype(auto) back () const — same last-element energy, but const. she's chill.
• constexpr auto cbegin () — const iterator to the beginning, non-const object.
• constexpr auto cbegin () const — const iterator to the beginning, and the object is const too.
• constexpr auto cend () — const iterator to the end. the sequel.
• constexpr auto cend () const — const iterator to the end, const object. periodt.
• constexpr auto data () const noexcept(noexcept(ranges::begin(_M_derived()))) — pointer to the underlying data, const flavor.
• constexpr auto data () noexcept(noexcept(ranges::begin(_M_derived()))) — pointer to the underlying data, and yes the noexcept is conditional on ranges::begin(_M_derived()) not throwing. iykyk.
• constexpr bool empty () const noexcept(noexcept(_S_empty(_M_derived()))) — is it empty? const, and its noexcept rides on _S_empty(_M_derived()).
• constexpr bool empty () const noexcept(noexcept(ranges::size(_M_derived())==0)) — is it empty, const, and this time the noexcept rides on ranges::size(_M_derived())==0.
• constexpr bool empty () noexcept(noexcept(_S_empty(_M_derived()))) — the non-const "is it empty", noexcept from _S_empty(_M_derived()).
• constexpr bool empty () noexcept(noexcept(ranges::size(_M_derived())==0)) — non-const "is it empty", noexcept from ranges::size(_M_derived())==0.
• constexpr decltype(auto) front () — first element. main character position.
• constexpr decltype(auto) front () const — first element, const edition.
• constexpr operator bool () const noexcept(noexcept(ranges::empty(_M_derived()))) — the const conversion to bool, and it won't throw unless ranges::empty(_M_derived()) does.
• constexpr operator bool () noexcept(noexcept(ranges::empty(_M_derived()))) — the non-const conversion to bool, same noexcept deal.
• template<random_access_range _Range = _Derived> constexpr decltype(auto) operator[] (range_difference_t< _Range > __n) — indexed access, but only if _Range is a random_access_range, and _Range defaults to _Derived. takes a range_difference_t< _Range > __n.
• template<random_access_range _Range = const _Derived> constexpr decltype(auto) operator[] (range_difference_t< _Range > __n) const — same subscript, const version, and here _Range defaults to const _Derived.
• constexpr auto size () const noexcept(noexcept(_S_size(_M_derived()))) — how big is it, const, noexcept from _S_size(_M_derived()).
• constexpr auto size () noexcept(noexcept(_S_size(_M_derived()))) — how big is it, non-const, same noexcept situation.

that's twenty functions. twenty. we counted. 💅
