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: common.rs
    path of file: ./repos/CYFS/src/tools/cyfs-meta-client/src
    
    the code of the file until where you have to start completion: use clap::{ArgMatches, Arg};
use std::path::Path;
use async_recursion::async_recursion;
use log::*;
use lazy_static::lazy_static;
use cyfs_base::{BuckyResult, ObjectId, NameLink, BuckyError, BuckyErro
    
pub fn get_caller_arg<'a, 'b>(name: &'a str, short: &'a str, default: Option<&'a str>) -> Arg<'a, 'b> {
    let mut arg = Arg::with_name(name).short(short).long(name).takes_value(true).required(true)
        .help("desc and sec file path, exclude extension");
    if let Some(default) = default {
        arg = arg.default_value(default);
    }
    arg
}
