There isn't at the moment.

However, Beman Dawes has recently updated his proposed Boost.Endian
library (http://tinyurl.com/4bswsh), and there is a discussion about
it over on the dev list
(http://lists.boost.org/Archives/boost/2008/05/137820.php and
followups).

It would allow you to say (something like)

struct // or class
{
   boost::endian::uint_t<16, boost::endian::big_endian> first;
   boost::endian::uint_t<32, boost::endian::big_endian> second;
} data;

Which you could then std::copy your data into (through char*s), and
use the implicit conversions to get native integral types out.
