Maybe you can have a look at biniou from Martin Jambon:

http://mjambon.com/biniou.html

Once your data structure is described, biniou will generate
automatically the {un}marshalling code for you.

binprot from janestreet does this also, maybe in an even more automatic
way, but I never used it.

I know I don't really exactly answer your initial question, sorry.
