constexpr void satisfy();		(seit C++20) (nur Exposition*)

Überspringt leere innere Bereiche und initialisiert den zugrundeliegenden Iterator inner_.

Sei die Konstante /*ref-is-glvalue*/ std::is_reference_v<ranges::range_reference_t<Base>>.

Der Funktionskörper ist äquivalent zu

auto update_inner = [this](const ranges::iterator_t<Base>& x) -> auto&&
{
    if constexpr (/*ref-is-glvalue*/)     // *x is a reference
        return *x;
    else
        return parent_->inner_./*emplace-deref*/(x);
};
 
for (; outer_ != ranges::end(parent_->base_); ++outer_)
{
    auto&& inner = update_inner(outer_);
    inner_ = ranges::begin(inner);
    if (inner_ != ranges::end(inner))
        return;
}
 
if constexpr (/*ref-is-glvalue*/)
    inner_ = InnerIter();
