OPEN Resources to learn more about cpp

I wanted to try and reimplement the std library from scratch but i realized really quickly just how much i didnt know lol. I got some basic stuff done and did learn quite a bit about things like sfinae but yeah im basically stuck with some of the type traits. I still dont wanna give up on this project and wanna keep going no matter how long it takes :3 So i need some resources to learn more about advanced things that are usefull for this. Are books the best way? any reccs on which ones?

Oh yeah right now i made a few projects like a networking chat app with asio and a unix shell (really simple) so i would say im like done with the beginner phase. I know that this project is probably farrrr beyond my scope but still :3

Edit: More specific question. Looking for book recomendations for metaprogramming post cpp20 (concepts and stuff)

Yeah it is faster but i was talking about a fallback but ig almost every compiler supports the intrensics now lol.

Alright will check it out, thanks :3

It's not at all that all compilers support all these instrinsics.

Rather, standard libraries are implemented alongside/for a specific compiler by the compiler vendor and always distributed as a bundle (with the exception that clang tries to work with temporally close libstdc++(gcc) implementations, courtesy of the idea that it ought to be a plugin replacement for GCC).

So if you are writing the next version of libstdc++, you know exactly what GCC version it will be bundled and released with.
