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: 01_quick.rs
    path of file: ./repos/clap/examples/tutorial_derive
    
    the code of the file until where you have to start completion: use std::path::PathBuf;

use clap::{Parser, Subcommand};

#[derive(Parser)]
#[command(version, about, long_about = None)]
struct Cli {
    /// Optional name to operate on
    name: Option<String>,

    /// Sets a custom config file
    #[arg(short, long, value_name = "FILE")]
    config: Option<PathBuf>,

    /// Turn debugging information on
    #[arg(short, long, action = clap::ArgAction::Count)]
    debug: u8,

    #[command(subcommand)]
    command: Option<Commands>,
}

#[derive(Subcommand)]
enum Commands {
    /// does testing things
    Test {
        /// lists test values
        #[arg(short, long)]
        list: bool,
    },
}

fn main() {
    let cli = Cli::parse();

    // You can check the value provided by positional arguments, or option arguments
    if let Some(name) = cli.name.as_deref() {
        println!("Value for name: {name}");
    }

    if let Some(config_path) = cli.config.as_deref() {
        println!("Value for config: {}", config_path.display());
    }

    // You can see how many times a particular flag or argument occurred
    // Note, onl

    }

    if let Some(config_path) = cli.config.as_deref() {
        println!("Value for config: {}", config_path.display());
    }

    // You can see how many times a particular flag or argument occurred
    // Note, only flags can have multiple occurrences
    match cli.debug {
        0 => println!("Debug mode is off"),
        1 => println!("Debug mode is kind of on"),
        2 => println!("Debug mode is on"),
        _ => println!("Don't be crazy"),
    }

    // You can check for the existence of subcommands, and if found use their
    // matches just as you would the top level cmd

        Some(Commands::Test { list }) => {
            if *list {

            } else {

            }
        }
        None => {}
    }

    // Continued program logic goes here...
