I literally cannot share the source, I wish I could but the reality is my job does not let me. You're being unreasonable given how
ridiculously simple the benchmarked section of the code is: it would not take long for even a Rust beginner to reimplement something equivalent, especially since it doesn't touch on any of the "hard" parts of Rust (no need for explicit lifetimes etc.).
As I said before, I have nothing to gain and everything to lose by lying to you.
