@Alrighttt Hi, one of the tests is failing. Pinging you in case you didn’t see it

This is utilizing an unmaintained project, actions-rs. Could you please research an alternative?

The github runner should have rustup by default. It doesn't seem necessary to use an action.

    - name: Install Rust toolchain
      run: |
        rustup install nightly-2023-06-01 --profile minimal --component clippy rustfmt
        rustup default nightly-2023-06-01

I believe it could be as simple as this.
