Can someone of you have a quick look to this? by quick searching I found this repo to install Rust, but I wonder if that is too much and I should go back to straight install as done here - what do you think?

also I realized the poe commands don't need to go under the patch (only the true hoooking)

Eventually I want to also add fmt and clippy, but as far as I understood that requires the packages top level and this will be realized after #375

The toolchain action is considered canonical as far as I know. I can't access the other link (It only shows 'Forbidden').

thanks, so I assume it is fine

the other link said something like

- name: Update local toolchain
        run: |
          rustup update
          rustup component add clippy
          rustup install nightly
