I had written something like this and found a very interesting compiler difference between clang/gcc and MSVC. I used lambdas as parsers, which worked great for the first two compilers. Did not work at all for MSVC. It would not compil

Having read through the README, I'm not quite sure what makes this perform better than other systems. I can see that it will perform excellent when iterating over a single type as all entries for this type are next to each other. Howev

I don't get what point is the author is trying to make. If it is to show that Rust outperforms C++ when implementing COW, I think he is mistaken. COW is intrinsically performance limited in multithreaded environments, this is not a lan
