std::ranges...:value_type(3)

okay so first things first: this page is std::ranges...:value_type(3) from the C++ Standard Libary — yes, that’s the manual name, typo included, and we’re keeping it 💖.

💖 NAME 💖

std::ranges::lazy_split_view::outer_iterator::value_type - std::ranges::lazy_split_view::outer_iterator::value_type

That’s literally the whole NAME, bestie. No cap. 🫶

✨ Synopsis ✨

struct value_type : ranges::view_interface<value_type>  (since C++20)

The value type of the iterator ranges::lazy_split_view<V, Pattern>::/*outer_iterator*/<Const>.

🌸 Member functions 🌸

• constructor (C++20) — constructs a value_type object (public member function)
• begin (C++20) — returns an inner_iterator to the beginning of the inner range (public member function)
• end (C++20) — returns a std::default_sentinel (public member function)

💜 Inherited from std::ranges::view_interface 💜

• empty (C++20) — returns whether the derived view is empty. Provided if it satisfies sized_range or forward_range. (public member function of std::ranges::view_interface<D>)
• cbegin (C++23) — returns a constant iterator to the beginning of the range. (public member function of std::ranges::view_interface<D>)
• cend (C++23) — returns a sentinel for the constant iterator of the range. (public member function of std::ranges::view_interface<D>)
• operator bool (C++20) — returns whether the derived view is not empty. Provided if ranges::empty is applicable to it. (public member function of std::ranges::view_interface<D>)
• front (C++20) — returns the first element in the derived view. Provided if it satisfies forward_range. (public member function of std::ranges::view_interface<D>)

🎀 Member functions 🎀

Now the actual member-function details, bestie — same section name, more lore 💅.

🌟 std::ranges::lazy_split_view::outer_iterator::value_type::value_type 🌟

value_type() = default;                              (1) (since C++20)
constexpr explicit value_type(/*outer_iterator*/ i); (2) (since C++20)

1. Value initializes the i_ via its default member initializer (= /*outer_iterator*/()).
2. Initializes i_ with std::move(i).

🦋 std::ranges::lazy_split_view::outer_iterator::value_type::begin 🦋

constexpr /*inner_iterator*/<Const> begin() const;  (since C++20)

Equivalent to return /*inner_iterator*/<Const>{i_};.

🍓 std::ranges::lazy_split_view::outer_iterator::value_type::end 🍓

constexpr std::default_sentinel_t end() const noexcept;  (since C++20)

Returns std::default_sentinel.

💀 Defect reports 💀

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

• DR: LWG 3593 — Applied to: C++20 — Behavior as published: end always returns std::default_sentinel but might not be noexcept — Correct behavior: made noexcept.
