> This change came about when I looked at how to tie the object container and
> http changes to the serializer.
> The current implementation of C++ allows serialization to and from C++
> iostreams. However, typically I want to serialize to a buffer, which I can
> write to disk or network (or both). While iostreams do buffering, they're
> not well-suited if you just want to store to memory (the unittest examples
> serialize to ostringstream then extract the data as a string--not so
> efficient).
> So I've added a buffering library, that does page-backed allocations (adds a
> page as buffer grows). It also supports the concept classes defined by
> boost::asio for Constant and Mutable buffer sequences (this allows the
> buffers to be used directly in asio networking calls), conversion to iovec,
> appending of foreign buffers, and iostream interface wrapper, so it's pretty
> flexible in the way it can be used.
