Let current_ denote the underlying tuple-like object of iterators to elements of adapted views.

1,2) Returns the iterator i incremented by n . Equivalent to: auto r = i ; r + = n ; return r ; .
3) Returns the iterator i decremented by n . Equivalent to: auto r = i ; r - = n ; return r ; .
4) Let DIST(k) be difference_type ( std :: get < k > ( i. current_ ) - std :: get < k > ( j. current_ ) ) . Returns the smallest absolute value among DIST(n) for all integers 0 <= n < sizeof... ( Views ) .

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

Parameters

i, j - the iterators.
n - position relative to current location.

Return value

1,2) a copy of i that is advanced by n
3) a copy of i that is advanced by - n
4) the distance between i and j
