Expected behavior

this project has doc tests which should contribute to the coverage. These tests are run by the cargo test workflow

[danieleades]

this is probably a tarpaulin issue, rather than an issue with the action

[intrepion]

Have you tried adding --docs to the command?

      - name: Run cargo-tarpaulin
        uses: actions-rs/[email protected]
        with:
          args: '--docs'

[danieleades]

@intrepion, yes thankyou. the issue was resolved in the linked tarpaulin issue
