I'd like to clarify the use case.
Lets say you're writing a client and a server, one is in python and
the other is C. If these 2 programs need to pass binary information
between them (lets say over a socket) there are 2 options, it could be
nice if you could only write the struct once (either in python or in
C) without any Cython or C extension (for portability and ease of
development's sake).
It's not as simple as that. You have to know the binary format layouts
(say, for floating point numbers) and struct padding that's used (since
it can be inserted arbitrarily) on the C side of things, not to mention
you have to arrange the whole the to be put into consistent (network)
byte order. Both sides have to take care of this, since if the server
and client are running on different architectures, there's no guarantees
any of these things will be the same.
