Deduction guides

 

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>.

Data members

Member	Definition
outer_iterator i_ (private)	An iterator into underlying view of the outer class (exposition-only member object*)

Member functions

(constructor) (C++20)	constructs a value_type object (exposition-only 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	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	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	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

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

constexpr explicit value_type(/*outer_iterator*/ i); // exposition only		(since C++20)

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.

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

DR	Applied to	Behavior as published	Correct behavior
LWG 3593	C++20	end was not be noexcept	made noexcept
LWG 4013	C++20	value_type was default-initializable	not default-initializable
