The code coverage script mentioned in the README.md does not work.

  note: selecting a toolchain with `+toolchain` arguments require a rustup proxy; see <https://rust-lang.github.io/rustup/concepts/index.html>

@philippecamacho it works well on my side with ahash 0.8.11, maybe try cargo update first?

@mrain This worked thank you. I had to update flake.nix though to be able to run the script. See #621.
