I've just updated the Rust version to the benchmark monitor could 
work on Linux (it only worked on Mac before) :D that's probably 
why your rustc didn't work, though as the project is still using 
edition2018 I would've thought even a very old compiler would 
have worked... anyway, if you ever find yourself actually using 
Rust, you should use `rustup` (https://rustup.rs/) which makes it 
trivial to update Rust.

About the "count" option: I had assumed you didn't call format on 
the count option as it's never needed, there's nothing to print.
