Increments or decrements the iterator.
Let current_, end_, stride_, and missing_ be the data members of the iterator.
1,2) Equivalent to
auto r = i; r += n; return r;.
3) Equivalent to
4) Let auto r = i; r -= n; return r;.N be x.current_ - y.current_. Returns: -
(N + x.missing_ - y.missing_) / x.stride_, ifBasemodelsforward_range. -
-/*div-ceil*/(-N, x.stride_), ifN < 0. -
/*div-ceil*/(N, x.stride_)otherwise.
5) Equivalent to
return /*div-ceil*/(x.end_ - x.current_, x.stride_);.
6) Equivalent to
return -(s - x);.These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when stride_view::iterator<Const> is an associated class of the arguments.
Parameters
| x, y, i | - | the iterators |
| s | - | a sentinel |
Return value
1,2) An incremented iterator
3) A decremented iterator
4) A distance between given iterators
5,6) A distance between given iterator and sentinel
