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: util.rs
    path of file: ./repos/vagga/src/wrapper
    
    the code of the file until where you have to start completion: use std::path::{Path, PathBuf};
use std::collections::BTreeMap
    
pub fn warn_if_data_container(container_config: &Container) {
    if container_config.is_data_container() {
        warn!("You are trying to run command inside the data container. \
            Data containers is designed to use as volumes inside other \
            containers. Usually there are no system dirs at all.");
    }
