Does it really work?

Does it really work? Two different people on two different computers (Windows and Ubuntu) tried to compile this. Both get the same error (see below). Searching for a solution on the Internet did not give a result.

Hi, sorry for the late reply, not sure how I missed it.

That error is Rust specific, you need to compile on nightly. I believe this was for benchmarks; I used it because Criterion testing times were very large.
