Re: [boost] [database] - guid class

< snip >

By the way, by looking more carefully your interface, I didn't see how to have a reading access to the raw struct of the guid: attribute guid;;_data, more precisely, to the raw data pointer: guid::_data.elems. This reading access could be useful for low level access. Does that make sense?

This does make sense. I have added a constructor to initialize from raw data: template <ByteInputIterator> guid(ByteInputIterator first, ByteInputIterator last); and a function to get out the raw bytes: template <ByteOutputIterator> void output_bytes(ByteOutputIterator out) { std::copy(data_.begin(), data_.end(), out); } Is output_bytes what you are looking for?
