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: set.rs
    path of file: ./repos/cargo-trim/src/command
    
    the code of the file until where you have to start completion: use anyhow::Result;
use clap::Parser;

use crate::config_file::ConfigFile;
#[derive(Debug, Parser)]
#[command(about = "Set config file values", arg_required_else_help = true)]
pub(crate) struct Set {
    #[arg(
        long = "dry-run",
        short = 'n',
        help = "Run command in dry run mode to see what would be done"
    )]
    dry_run: bool,
    #[arg(
        long = "directory",
        short
    
    pub(super) fn run(&self, config_file: &mut ConfigFile) -> Result<()> {
        let dry_run = self.dry_run;
        if let Some(directories) = &self.directory {
            for directory in directories {
                let path_separator = std::path::MAIN_SEPARATOR;
                let path = directory.trim_end_matches(path_separator);
                config_file.add_directory(path, dry_run, true)?;
            }
        }
        if let Some(files) = &self.ignore {
            for file in files {
                config_file.add_ignore_file_name(file, dry_run, true)?;
            }
        }
        if self.scan_hidden_folder {
            config_file.set_scan_hidden_folder(true, dry_run, true)?;
        }
        if self.scan_target_folder {
            config_file.set_scan_target_folder(true, dry_run, true)?;
        }

        Ok(())
    }
