The core engine design for the plugin by different use case and context.
Currently its the CLI interface. If you have different programming or integration need, you can interact with the Core by is APIs.
```Rust let mut newparams = Params::default(); newparams.confpath = "../demo/conf/confjson.yaml".toowned(); newparams.mode = Mode::MASK; newparams.filetype = FileType::JSON;
let mut newapp = App::new(newparams.clone()).await.unwrap(); newapp.loadjob_config().await.unwrap();
let metrics = new_app.process().await.unwrap(); ```
