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: config.rs
    path of file: ./repos/bacon/src
    
    the code of the file until where you have to start completion: use {
    crate::*,
    anyhow::*,
    lazy_regex::regex_is_match,
    serde::Deserialize,
    std::{
        collections::HashMap,
        fs,
        path::Path,
    },
};

/// A configuration item which may be stored either as `bacon.toml`
/// along a `Cargo.toml` file or as `prefs.toml` in the xdg config directory.
///
/// Leaf values are options (and not Default) so that they don't
    
    pub fn from_path(path: &Path) -> Result<Self> {
        let conf = toml::from_str::<Self>(&fs::read_to_string(path)?)
            .with_context(|| format!("Failed to parse configuration file at {:?}", path))?;
        for (name, job) in &conf.jobs {
            if !regex_is_match!(r#"^[\w-]+$"#, name) {
                bail!("Invalid configuration : Illegal job name : {:?}", name);
            }
            if job.command.is_empty() {
                bail!("Invalid configuration : empty command for job {:?}", name);
            }
