| # This workflow comments on a PR with the results of the `cargo bloat check` performed in the performance workflow. | |
| # This is a workaround for the limitations imposed by GitHub Actions on workflows triggered by pull requests from forked repositories. | |
| # The restrictions apply to the pull_request event triggered by a fork opening a pull request in the upstream repository. | |
| # - Events from forks cannot access secrets, except for the default GITHUB_TOKEN. | |
| # - The GITHUB_TOKEN has read-only access when an event is triggered by a forked repository. | |
| # | |
| # These restrictions mean that during a pull_request event triggered by a forked repository, | |
| # actions have no write access to GitHub resources and will fail on any attempt. | |
