## Get Started

This is a Rust project, so [rustup](https://rustup.rs/) is the best place to start.

This is a pure rust project, so only `cargo` is needed.

- `cargo check` to analyze the current package and report errors.
- `cargo build` to compile the current package.
- `cargo clippy` to catch common mistakes and improve code.
- `cargo test` to run unit tests.
- `cargo bench` to run benchmark tests.

Useful tips:

- Check/Build/Test/Clippy all code: `cargo <cmd> --tests --benches --examples`
- Test specific function: `cargo test tests::it::services::fs`

## Test

Copy `.env.example` to local, change needed test suite values.

```shell
cargo test
```
