1944279 - Use nightly rust toolchain in GitHub action

Status: RESOLVED FIXED

(Webtools :: Searchfox, task)

Description

[Tooru Fujisawa [:arai]]

It looks like the GitHub action's environment has ~/.cargo by default (or at least before common-provision-pre.sh checks it),
and apparently it's not the latest nightly.
https://github.com/arai-a/mozsearch/actions/runs/13009914725/job/36285122759

As explained in bug 1943521, the SCIP symbol syntax is changed in the latest rust-analyzer nightly and the test snapshot is updated to follow it.
In order to make the test pass, the GitHub action's env should also use the latest rust-analyzer nightly.

The provisioning scripts already try to install Rust nightly, but this is skipped over because the GitHub Actions runner already has $HOME/.cargo.

I think we can just extract this block from the if:

rustup install nightly
rustup default nightly
rustup uninstall stable
rustup component add rust-analyzer

I'll send a PR to test this.
