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: package.rs
    path of file: ./repos/holochain-rust/crates/cli/src/cli
    
    the code of the file until where you have to start completion: use crate::{config_files::Build, error::DefaultResult, util};
use base64;
use colored::*;
use holochain_core::wasm_engine::{run_dna, WasmCallData};
use holochain_core_type
    
fn hdk_version_compare(hdk_version: &HDKVersion, cargo_toml: &str) -> DefaultResult<bool> {
    let toml: Value = toml::from_str(cargo_toml)?;
    let dependancies = toml
        .get("dependencies")
        .ok_or_else(|| format_err!("Could not get dependencies"))?;
    let hdk = dependancies
        .get("hdk")
        .ok_or_else(|| format_err!("Could not get HDK"))?;
    let tag = hdk
        .get("tag")
        .ok_or_else(|| format_err!("Could not get HDK tag"))?
        .as_str()
        .ok_or_else(|| format_err!("Could not parse string"))?;
    let hdk_version_from_toml = HDKVersion::new(tag)?;
    Ok(hdk_version == &hdk_version_from_toml)
}
