current

https://github.com/xd009642/tarpaulin prints inconsistent test coverage

example, cargo tarpaulin -p types prints:

expected

1. replace tarpaulin with the source-based code coverage tool cargo-llvm-cov in:
   1. workflows - 2 hours
   2. devcontainers - 2 hours
2. add cargo-llvm-cov as a make test target - 1 hour
3. also, add the workflow_run event to trigger the dev-rule.yaml workflow after the dev-crates.yaml completes - 1 hour
