Letinner_ denote the underlying iterator.
1,2) Returns the iteratori incremented byn. Equivalent to:return/*iterator*/(*i.parent_, i.inner_+ n);.
3) Returns the iteratori decremented byn. Equivalent to:return/*iterator*/(*i.parent_, i.inner_- n);.
4) Calculates thedistance betweeni andj. Equivalent toreturn i.inner_- j.inner_;.
This function is not visible to ordinaryunqualified orqualified lookup, and can only be found byargument-dependent lookup whenzip_transform_view::iterator<Const> is an associated class of the arguments.
