rust-lang/rust-analyzer GitHub Actions scorecard

Workflow runs on both push and pull_request · Coverage

Pushing to a branch and opening a PR triggers two runs. Pick one (usually `pull_request`) and exclude branch pushes for non-default branches.

on:
  push:
    branches: [main]
  pull_request:

No concurrency control · Coverage

Add a `concurrency:` block keyed on branch to cancel superseded runs when devs push twice quickly.

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: true

Missing dependency cache · release

Add `Swatinem/rust-cache@v2` (the de-facto cargo cache), or an `actions/cache@v4` step keyed on `Cargo.lock`.

- uses: Swatinem/rust-cache@v2

No path filters on triggers · CI

Runs on every push/PR with no `paths:` filter, so docs-only changes still trigger full CI. Add a `paths:` filter if that's common.

on:
  pull_request:
    paths:
      - 'src/**'
      - 'package.json'

Premium runners (macOS / Windows) · CI

macOS bills ~10× and Windows ~2× a Linux minute. The cost estimate above assumes Linux, so your real spend is higher. Move any job that doesn't need them to `ubuntu-latest`.

jobs:
  build:
    runs-on: ubuntu-latest  # ~10x cheaper than macos-latest

No job timeout · Coverage

No job sets `timeout-minutes`, so a hung step can run to GitHub's 6-hour default. Add `timeout-minutes` to each job.

jobs:
  build:
    runs-on: ubuntu-latest
    timeout-minutes: 15

Artifacts at default retention · metrics

`upload-artifact` has no `retention-days`, so artifacts keep up to 90 days (storage cost). Set e.g. `retention-days: 7`.

- uses: actions/upload-artifact@v4
  with:
    name: build
    path: dist/
    retention-days: 7
