Vscode-rust: Pasar variables de entorno a RLS

Tengo problemas con proyectos que incluyen diesel y usan variables de entorno, por ejemplo:

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))
}

Da como resultado lo siguiente en la ventana de resultados:

¿Hay alguna forma de pasar variables de entorno al RLS? O tal vez se deba establecer alguna ruta para que dotenv pueda descubrir la variable ambiental.
