std::ranges::adjacent_transform_view<V,F,N>::iterator<Const>::iterator

/*iterator*/() = default;
 (1) (since C++23) 
constexpr /*iterator*/( /*iterator*/<!Const> i )
    requires Const &&
        std::convertible_to</*inner-iterator*/<false>, /*inner-iterator*/<Const>>;
 (2) (since C++23) 
private:
constexpr /*iterator*/( Parent& parent, /*inner-iterator*/<Const> inner );
 (3) (exposition only*)

Construct an iterator.

1) Default constructor. Value-initializes the underlying pointer parent_ with nullptr, and default-initializes the underlying iterator inner_.
2) Conversion from /*iterator*/<false> to /*iterator*/<true>. Initializes the underlying pointer parent_ with i.parent_, and move constructs the underlying iterator inner_ with std::move(i.inner_).
3) This iterator also has a private constructor which is used by ranges::adjacent_transform_view::begin and ranges::adjacent_transform_view::end. This constructor is not accessible to users. Initializes parent_ with std::addressof(parent), and move constructs inner_ with std::move(inner).

Parameters

i - an /*iterator*/<false>
parent - an owning object of type adjacent_transform_view
inner - an iterator of type adjacent_transform_view::inner_iterator
