json_struct VS unconstexpr-cpp20

I made a header only library with good performance and low memory overhead to parse JSON straight into structs, and serialize structs to JSON. How to parse into non map/object types is configurable with template functions. json_struct

json_struct for serializing directly to and from structs. Its one header only and performs on par with RapidJSON.

Hi, I wrote JsonStruct. A header only library for parsing to and from structs. So I basically had the same problem: how to add metadata. I desided for having an additional macro. This leads to make it possible to add metadata to structs that you cannot modify for instance. Also, you can deside not to add metadata for all of the member of a struct. Please check it out! https://github.com/jorgen/json\_struct

Nice page! I have written a JSON header only library that parses and serializes to structs. Would you be interested in reviewing it? Performance is ok/good and I personally think usability is good as well :) https://github.com/jorgen/json_struct

Stateful metaprogramming via friend injections gives us the ability to capture and retrieve a compile time state. Thus, it is possible to create compile time counters, mutable constant expressions https://github.com/DaemonSnake/unconstexpr-cpp20, static reflection ```cpp template struct flag { friend consteval auto member_type(flag); };
