## AI overview

The article announces a CppCon 2025 talk about using C++26 compile-time reflection for high-speed JSON serialization and deserialization. It says the authors extended the simdjson library to test the approach and that the talk video is available on YouTube.

## Source excerpt

The next C++ standard (C++26) is getting exciting new features. One of these features is compile-time reflection. It is ideally suited to serialize and deserialize data at high speed. To test it out, we extended our fast JSON library (simdjson) and we gave a talk at CppCon 2025. The video is out on YouTube. Our ... Continue reading JSON and C++26 compile-time reflection: a talk
