(4) (since C++23)

Let parent_ and inner_ be the data members of the iterator.

1,2) Equivalent to return /*iterator*/(*i.parent_, i.inner_ + n);.
3) Equivalent to return /*iterator*/(*i.parent_, i.inner_ - n);.
4) Equivalent to return i.inner_ - j.inner_;.

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

Parameters

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

Return value

1,2) An incremented iterator.
3) A decremented iterator.
4) A distance between given iterators.
