| # Since this check is marked as "required", the action needs to run on | |
| # every PR. However, if there were no changes to Go files, there will | |
| # be no changes to the generated files, hence we don't need to check. | |
| # So this step checks which files have been changed, and allows the | |
| # rest of the workflow to be skipped if no Go files were changed. | |
