    Kaitai Struct: declarative language to generate binary data parsers in C++ / C# / Go / Java / JavaScript / Lua / Nim / Perl / PHP / Python / Ruby

    I'm aware there is Kaitai Struct which can handle binary parsing (deserializing). And I have some success previously with python Construct which can do both serialize & deserialize, but it's written in python.

  • reflecxx

    A static reflection framework for C++, using libclang.

    I have a library and tooling that using code generation will allow you to automatically generate serialization/deserialization to your custom binary format. It uses the visitor pattern and code generation for static reflection (eg iterating over fields of a struct). Check it out at Particularly it includes an automatic to/from json, which you could use as a starting point for how to write your own visitor.
