* CI Setup uses latest Rust stable docker image
    - Setup has 3 stages
        - build - runs clippy and unit tests
        - test - runs integration tests
        - publish - This stage publishes to [crates](https://crates.io). It expects a token variable named `CARGO_RELEASE_TOKEN`

* To run integration tests in CI, you need to setup some environment variables
