That sounds like what CGAL calls a Circulator; c.f.

I've found these handy when iterating through graph edges incident on a
vertex, when you need to start on a specific edge. It's been ages since I've
used them so I can't recall the exact use case. Makes me wonder whether
something like this already exists in boost graph.
