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: node.rs
    path of file: ./repos/moon/crates/cli/src/commands/init
    
    the code of the file until where you have to start completion: use super::prompts::prompt_version;
use super::InitOptions;
use crate::helpers::fully_qualify_version;
use dialoguer::theme::ColorfulTheme;
use dialoguer
    
fn detect_node_version_manager(dest_dir: &Path) -> AppResult<String> {
    Ok(if is_using_version_manager(dest_dir, ".nvmrc") {
        "nvm".to_owned()
    } else if is_using_version_manager(dest_dir, ".node-version") {
        "nodenv".to_owned()
    } else {
        String::new()
    })
}
