Vscode-rust: Umgebungsvariablen an RLS übergeben

Ich habe Probleme mit Projekten, die diesel enthalten und beispielsweise Umgebungsvariablen verwenden:

pub fn establish_connection() -> SqliteConnection {
    dotenv().ok();

    let database_url = env::var("DATABASE_URL").expect("DATABASE_URL must be set");

    SqliteConnection::establish(&database_url)
        .expect(&format!("Error connecting to {}", database_url))
}

Ergibt im Ausgabefenster folgendes:

Gibt es eine Möglichkeit, Umgebungsvariablen an das RLS zu übergeben? Oder vielleicht muss ein Pfad festgelegt werden, damit dotenv die Umgebungsvariable herausfinden kann.
