[Boost-users] what is a vertex_descriptor? (boost graph library)

So it looks like it's basically a 0-based integer. When I start adding
vertices to an empty graph, the first one comes back as 0, the second as 1,
third as 2...etc.

Is it always an integer? When is it not an integer?

I really want a way to easily convert vertex_descriptor's and
edge_descriptor's to and from strings. Any ideas?
