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: mod.rs
    path of file: ./repos/stork/stork-lib/src/config
    
    the code of the file until where you have to start completion: #![allow(clippy::module_name_repetitions)]

use serde::{Deserialize, Serialize};
use smar
    
    fn bad_toml_syntax_fails_with_toml_error() {
        let contents = r#"[input] {}"#;
        let error = Config::try_from(contents).unwrap_err();
        let computed = error.to_string();
        let expected = "Cannot parse config as TOML. Stork recieved error: `expected newline, found a left brace at line 1 column 9`";
        assert_eq!(computed, expected);
    }
