You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: health.rs
    path of file: ./repos/fuel-core/tests/tests
    
    the code of the file until where you have to start completion: use fuel_core::{
    database::Database,
    service::{
        Config,
        FuelService,
    },
};
use fuel_core_client::client::FuelClient;

#[tokio::test]
async fn health() {
    let srv = FuelService::from_database(Database::default(), Config::local_node())
        .await
        .unwrap();
    let client = FuelClient::from(
    
async fn can_restart_node() {
    use tempfile::TempDir;
    let tmp_dir = TempDir::new().unwrap();

    // start node once
    {
        use fuel_core::service::ServiceTrait;
        let database = Database::open(tmp_dir.path(), None).unwrap();
        let first_startup = FuelService::from_database(database, Config::local_node())
            .await
            .unwrap();
        first_startup.stop_and_await().await.unwrap();
    }

    {
        let database = Database::open(tmp_dir.path(), None).unwrap();
        let _second_startup = FuelService::from_database(database, Config::local_node())
            .await
            .unwrap();
    }
}
