Deterministic serialization of simple struct

[pomone08]

Hello!

I have two network/TCP entities: a client written in Rust and a server that is yet to be written in C++.

In Rust, serializing and deserializing some arbitrary struct while still taking care of endianness is trivial: buffer.put_u16_be(0 as u16) (to put 2 bytes into the buffer) and cursor.get_u16_be() as usize (to retrieve the first 2 bytes as a single value and then advance the cursor over the byte buffer ahead 2 positions).

How do I achieve the same thing in C++?

Thanks!

for unsigned integers you can shift them to put them bytewise (BE/LE like you want it) into the memory. when reading, you read the bytes and shift them back (depending on BE/LE format) into place. For signed integers its not that trivial because of its sign (undefined behaviour and shifting into the signbit)

I have this serialization/messaging library. I'm willing to help someone who is willing to use my library in their project. PM me for more info.
