如何在Github CI工作流程中缓存Cargo包？

Question

我有一个使用 Cargo 包的 GitHub CI。但每次运行 CI 时，大约需要花费时间。 6 分钟即可构建软件包。有没有办法缓存二进制文件，以便下次运行时不必再次构建它？

这就是我的 CI 的样子。

name: "Verify the specs of concrete tests using bulloak"

on: "workflow_call"

jobs:
  bulloak-check:
    runs-on: "ubuntu-latest"
    steps:
      - name: "Check out the repo"
        uses: "actions/checkout@v4"

      - name: "Install Rust"
        uses: "actions-rs/toolchain@v1"
        with:
          toolchain: "stable"

      - name: "Install bulloak or use the cached version"
        run: "cargo install bulloak"

      - name: "Verify the concrete tests"
        run: "bulloak check test/integration/concrete/**/**.tree --skip-modifiers"

      - name: "Bulloak summary"
        run: |
          echo "## Bulloak result" >> $GITHUB_STEP_SUMMARY
          echo "✅ Passed" >> $GITHUB_STEP_SUMMARY

您可以按以下方式缓存 Cargo 包（我已使用您的示例并将其修改为使用缓存）：

name: "Verify the specs of concrete tests using bulloak"

on: "workflow_call"

jobs:
  bulloak-check:
    runs-on: "ubuntu-latest"
    steps:
      - name: "Check out the repo"
        uses: "actions/checkout@v4"

      - name: "Install Rust"
        uses: "actions-rs/toolchain@v1"
        with:
          toolchain: "stable"

      - name: "Cache cargo"
        id: cache-cargo
        uses: "actions/cache@v4"
        with:
          path: |
            ~/.cargo/bin/
            ~/.cargo/registry/index/
            ~/.cargo/registry/cache/
            ~/.cargo/git/db/
            target/
          save-always: true
          key: ${{ runner.os }}-cargo-${{ hashFiles('**/Cargo.lock') }}
          restore-keys: ${{ runner.os }}-cargo-

      - name: "Install bulloak or use the cached version"
        if: steps.cache-cargo.outputs.cache-hit != 'true'
        run: "cargo install bulloak"

      - name: "Verify the concrete tests"
        run: "bulloak check test/integration/concrete/**/**.tree --skip-modifiers"

      - name: "Bulloak summary"
        run: |
          echo "## Bulloak result" >> $GITHUB_STEP_SUMMARY
          echo "✅ Passed" >> $GITHUB_STEP_SUMMARY
