Binary Object Serialization with Data Structure Traversal & Reconstruction in C++ - Chris Ryan - CppCon 2022
https://github.com/CppCon/CppCon2022

This talk will describe a minimally intrusive technique to add serialization to a set of classes, traversing hierarchical and non-hierarchical data, persisting in a binary format and dynamic reconstruction

When storing, it can deduce the data types using Template Argument Deduction (TAD) and safely protects against recursive reentrancy.
When loading, it uses a reflection type technique for dynamic object creation using an automatic serializable type registration mechanism.

Reflection as a language feature will be unavailable until at least C++26. This serialization technique can dynamically recreate a persisted complex data structure/structure network. This is a platform agnostic technique.

Not everybody is yet able to migrate to C++20, so this is using a C++14 compliant SFINAE/std::enable_if＜＞ mechanism. We will also explore optimizations and what it takes to convert this technique to use C++20 concepts.

The serialized data can be persisted to a disk file, shared memory for IPC or using network streams for live remote data sharing like HPC or gaming.

This is not trying to sell you on the use of the library but rather sharing metacppcon.digital-medium.co.uk/tag/programming/">programming techniques you can add to your toolbox.

Killing C++ Serialization Overhead & Complexity - Eyal Zedaka - CppCon 2022
https://github.com/CppCon/CppCon2022

One of the hottest topics in C++ being data serialization, which is a major enabler for inter process communication, persisting the state of the program, or storing information in convenient way. That’s why there are countless data serialization frameworks out there, even ones made for cross programming-language communication.

When considering a serialization framework we face many considerations - convenience of use, performance, size of the library, size of the data, is the library applicable for embedded, support for cross language communication, build system dependencies (for those requiring to generate code in build time), and many more.

If I got you wondering about the above, and you are looking for some modern C++20 zero overhead macro-less serialization that requires close to nothing from you as a developer, together with almost unmatched performance, freestanding/embedded support out of the box, and a fair chance to blow your mind, this session is for you, hope to see you there!
