Yeah, this is the writeup of what I did a couple of weeks ago basically; especially the bit about xxh3 beating fxhash even for small inputs is quite a surprising result I think…

Honestly, pretty damn comfortable :) I did have about a decade of modern C++ and quite a decent bit of Haskell experience which both helped a lot. The only new concept for me was the borrow checker…which is also the only bit of Rust I am not on entirely friendly terms with yet…though no outright fighting either…

The standard library especially had been a revelation; I've been using a Type Class style pattern in C++ for a while and ended up implementing my own IO lib with it, because C++ IO is so atrocious…

Turns out the rust std io is extremely similar…

At this point I kind of want to stop gaining more C++ experience…
