There is a Error, But it just a simple Demo Code.

use clap::{arg, command, Command};

fn main() {

let matches = command!() // requires `cargo` feature
    .propagate_version(true)
    .subcommand_required(true)
    .arg_required_else_help(true)
    .subcommand(
        Command::new("add")
            .about("Adds files to myapp")
            .arg(arg!([NAME])),
    )
    .get_matches();

match matches.subcommand() {
    Some(("add", sub_matches)) => println!(
        "'myapp add' was used, name is: {:?}",
        sub_matches.get_one::<String>("NAME")
    ),
    _ => unreachable!("Exhausted list of subcommands and subcommand_required prevents `None`"),
