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: diffsitter_utils.rs
    path of file: ./repos/diffsitter/src/bin
    
    the code of the file until where you have to start completion: //! Utility functions that complement the diffsitter binary.

use anyhow::Result;
use clap::CommandFactory;
use clap::FromArgMatches;
use clap::Parser;
use libdiffsitter::parse::construct_ts_lang_from_shared_lib;
use std::path::PathBuf;

/// Utility functions that complement the diffsitter
    
fn main() -> Result<()> {
    let command = DiffsitterUtilsApp::command();
    let matches = command.get_matches();
    let args = DiffsitterUtilsApp::from_arg_matches(&matches)?;
    match args {
        DiffsitterUtilsApp::LoadParser {
            language_name,
            parser_path,
        } => {
            construct_ts_lang_from_shared_lib(&language_name, &parser_path)?;
        }
    };
    Ok(())
}
