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: main.rs
    path of file: ./repos/Lure/src
    
    the code of the file until where you have to start completion: mod config;
mod connection;
mod keypair;
mod lure;
mod utils;

use anyhow::anyhow;
use std:
    
async fn main() -> Result<(), Box<dyn Error>> {
    let current_dir = env::current_dir()?;
    let config_file = current_dir.join("settings.toml");
    let config_file_path = config_file.to_str().ok_or(anyhow!("Failed to get config file path"))?;

    println!("{}", config_file_path);

    let config = match LureConfig::load(config_file_path) {
        Ok(config) => {
            // Save config to fill missing fields
            let _ = config.save(config_file_path);
            Ok(config)
        },
        Err(error) => {
            match error {
                LureConfigLoadError::Io(_) => {
                    // If config loading fails we generate a default config
                    let default_config = LureConfig::default();
                    // Save the config to disk
                    let _ = default_config.save(config_file_path);
                    Ok(default_config)
                },
                LureConfigLoadError::Parse(parse_error) => Err(parse_error)
            }
        },
