Berechnet den Abstand (in Anzahl von Chunks) zwischen dem Iterator und dem Sentinel.

Sei parent_ der zugrundeliegende Zeiger auf die umschließende chunk_view.

1) Äquivalent zu

const auto dist = ranges::end(i.parent_->base_) - *i.parent_->current_;
if (dist < i.parent_->remainder_)
    return dist == 0 ? 0 : 1;
return /*div-ceil*/(dist - i.parent_->remainder_, i.parent_->n_) + 1;

2) Äquivalent zu: return -(s - i);.

Diese Funktionen sind nicht für normale unqualifizierte oder qualifizierte Lookups sichtbar und können nur durch argumentabhängige Lookups gefunden werden, wenn std::ranges::chunk_view::outer-iterator eine zugehörige Klasse der Argumente ist.

Parameter

i	-	der Iterator
s	-	das Sentinel

Rückgabewert

Der Abstand zwischen dem gegebenen Iterator und dem Sentinel.
