Führt Iterator-Arithmetik durch oder berechnet die Distanz.

Seien current_, end_, n_ und missing_ die zugrunde liegenden Datenmember.

Äquivalent zu

1,2) auto r = i; r += pos; return r;.

3) auto r = i; r -= pos; return r;.

4) return (i.current_ - j.current_ + i.missing_ - j.missing_) / i.n_;.

5) return /*div-ceil*/(i.end_ - i.current_, i.n_);.

6) return -(y - x);.

Diese Funktionen sind für gewöhnliche unqualifizierte oder qualifizierte Suche nicht sichtbar und können nur durch argumentabhängige Suche gefunden werden, wenn chunk_view::iterator<Const> eine assoziierte Klasse der Argumente ist.

Parameter

i, j	-	die Iteratoren
pos	-	Die Position relativ zur aktuellen Position

Rückgabewert

1,2) Ein erhöhter Iterator.

3) Ein verringerter Iterator.

4) Ein Abstand (in Anzahl der Elemente, d.h. Chunks) zwischen den gegebenen Iteratoren.

5,6) Ein Abstand (in Anzahl der Elemente) zwischen dem gegebenen Iterator und Sentinel.
