Compatibility with Arduino

[titusfx]

Hi, I'm trying to add this library to arduino, but they don't use constexpr I-m trying to convert it to Macro but I'm failing.
There is a version or something to this matter? Thanks

This library makes heavy use of many C++17 features so it's fairly far from Arduino compatible by my understanding.

If you were to traverse back in the commit history you'd find versions that work with older C++ versions (https://github.com/TheNitesWhoSay/RareCpp/tree/e196af78fff80374ed435aa7ea5b29a5618e0233) but not with the same ease/depth of use nor cross-compiler support.

Without constexpr if/C++17 you'll likely need something similar to the "lambda guards" I had back then

RareCpp/CppRandomAccessReflectionLib/Reflect.h

Line 519 in e196af7

/// Lambda guards: the call to function will only be generated by the compiler if the type fits the guard category

, but at the time I wasn't able to get these externalized from fields nor was I able to recursively examine field contents https://github.com/TheNitesWhoSay/RareCpp/blob/e196af78fff80374ed435aa7ea5b29a5618e0233/CppRandomAccessReflectionLib/Json.h

You can give it a shot (and if you had a fork & a particular problem area I could take a stab at it) but I imagine an Arduino adaption would need to be built from the ground up using the current code as a guide rather than just changing a few things.
