Correct, boost::uuids::uuid is copyable, it is a POD.

It can be used as the key in an std::map. I have created a simple test for this and checked it into trunk (http://svn.boost.org/svn/boost/trunk/libs/uuid/test/test_uuid_in_map.cpp). It passes. I have also attached the file.

Ok that's what I thought at the time.

I'm not sure where the problem is with your code. Could you provide a more complete example?

I think my case was a mix of different library values not playing well together so in the end I used the only type commonly used in both libraries, and it was std::string.

So I think it was not directly a problem with uuid. My memory is not clear on the exact problem, sorry.
