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: new.rs
    path of file: ./repos/tectonic/src/bin/tectonic/v2cli/commands
    
    the code of the file until where you have to start completion: use clap::Parser;
use std::env;
use std::path::PathBuf;
use tectonic::{
    config::PersistentConfig, ctry, docmodel::WorkspaceCreatorExt, errors::Result, tt_note,
};
use tect
    
    fn customize(&self, _cc: &mut CommandCustomizations) {}

    fn execute(self, config: PersistentConfig, status: &mut dyn StatusBackend) -> Result<i32> {
        tt_note!(
            status,
            "creating new document in directory `{}`",
            self.path.display()
        );

        let wc = WorkspaceCreator::new(self.path);
        ctry!(
            wc.create_defaulted(config, status, self.web_bundle);
            "failed to create the new Tectonic workspace"
        );
        Ok(0)
    }
}
