I contacted Roy off-list yesterday to inquire about using packed ranges. It's probably a good idea for me to continue the discussion on the list so others can benefit from my learning experience. So, here goes!
So far I've managed to get the 4 key methods stubbed out with the right template arguments compiled and running: packable_size, pack, unpacked and packed_size I must say that it took me a bit of time to understand the difference between "packed_size" and "packable_size". Just to disclose that here, the former is called during unpack while the latter is called during pack. Makes sense now. I did run into one hitch that I wasn't able to get around cleanly. The various packed range receiving operations take output iterators to fill a container somewhere. I wasn't able to figure out what to do here. Using the standard iterators (like back_inserter) failed with missing operators errors or other template instantiation problems. As a workaround, I snagged the mesh_insert_iterator and was able to adapt it so my code compiles. Is this an unintended consequence of all this heavy templating? It seems like we should be able to use a standard insert iterator here with any old container (unless I'm just doing something plain wrong). Anyway, I haven't successfully implemented the routines to actually move the data yet but I can see that they are being called as expected so it's just a matter of filling in the details now. I'm excited about using this capability!
