Let inner_ denote the underlying iterator.

1,2) Returns the iterator i incremented by n . Equivalent to: return /*iterator*/ ( * i. parent_ , i. inner_ + n ) ; .
3) Returns the iterator i decremented by n . Equivalent to: return /*iterator*/ ( * i. parent_ , i. inner_ - n ) ; .
4) Calculates the distance between i and j . Equivalent to return i. inner_ - j. inner_ ; .

This function is not visible to ordinary unqualified or qualified lookup , and can only be found by argument-dependent lookup when zip_transform_view:: iterator <Const> is an associated class of the arguments.
