24.7.11.4 Class split_­view​::​outer-iterator​::​value_­type [range.split.outer.value]

namespace std::ranges {
  template<class V, class Pattern>
  template<bool Const>
  struct split_view<V, Pattern>::outer-iterator<Const>::value_type
    : view_interface<value_type> {
  private:
    outer-iterator i_ = outer-iterator();               // exposition only
  public:
    value_type() = default;
    constexpr explicit value_type(outer-iterator i);

    constexpr inner-iterator<Const> begin() const requires copyable<outer-iterator>;
    constexpr inner-iterator<Const> begin() requires (!copyable<outer-iterator>);
    constexpr default_sentinel_t end() const;
  };
}
constexpr explicit value_type(outer-iterator i);
Effects: Initializes i_­ with std​::​move(i).
constexpr inner-iterator<Const> begin() const requires copyable<outer-iterator>;
Effects: Equivalent to: return inner-iterator<Const>{i_­};
constexpr inner-iterator<Const> begin() requires (!copyable<outer-iterator>);
Effects: Equivalent to: return inner-iterator<Const>{std​::​move(i_­)};
constexpr default_sentinel_t end() const;
Effects: Equivalent to: return default_­sentinel;
