The code in book is in C++ and several of the exercises assume you are experimenting with the provided renderer. I seem to remember at least one exercise caused me to learn quite a bit about AVX intrinsics to see if I could beat the compiler at vector math. Rust may be tricky because you will need to render pixels in parallel, and most higher level languages will take a lot of skill to make fast.
