To run the benchmark please use a nightly compiler as it's required by the library.
You can define the project to use the nightly compiler with rustup override set nightly (assuming you have rustup on your system)
You can run the benchmark using either cargo bench or cargo criterion the former does not require any configuraction but the later is recommended. To use cargo criterion first you have to install it
cargo install cargo-criterion
Then you can use the command to run the benchmark.
I couldn't get cargo criterion to work on my machine, a windows 10 notebook, but with WSL2 with Ubuntu 20.04 it works fine
