sccache-stats

Record what sccache delivered as cache.sccache.* facts in the step summary and for the timing-report Cache section, plus the raw sccache --show-stats output in a log group. Use it as a late step after the builds it accounts for, in jobs that ran sccache.

Usage

- uses: gronke/ci/.github/actions/rust/sccache-stats@v3
  if: always()

Inputs

None.

Notes

• A no-op unless RUSTC_WRAPPER is an executable whose --version reports sccache, however it was installed.
• Records cache.sccache as <hits> hits / <misses> misses of <requests> compile requests, and cache.sccache.errors when the error count is not zero.
• The facts need jq; without it only the log group is written.
• The facts render as a small table in the step's own summary, so they show without timing-report.
• Never fails the job: a broken stats query costs the numbers, not the build.
• Composite actions have no post hooks, hence the separate late step, the same split as rust-cache and rust-cache-save.
