Sorry if it looked like I was being harsh on you particularly, I was not... I was being harsh on people making comments like "this Rust code is very slow" without showing their faster code, making suggestions that would almost certainly be slower or not even compile and other similar things I observed in this thread.

Never believe anyone saying "this could be much faster" without showing their code so people can actually check it.

I will believe the OP's code is slow when I see a faster implementation, which I haven't.
