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: dump.rs
    path of file: ./repos/Replibyte/replibyte/src/commands
    
    the code of the file until where you have to start completion: use std::fs::File;
use std::io::{stdin, BufReader, Error, ErrorKind, Read};
use std::sync::mpsc;
use std::time::Duration;

use timeago::Formatter;

use crate::cli::{DumpCreateArgs, DumpDeleteArgs};
use crate::cli::{RestoreArgs, RestoreLocalArgs};
use crate::config::{Config, ConnectionUri};
use crate::datastore::Datastore;
use crate::datastore::ReadOptions;
use crate::destination::generic_stdout::GenericStdout;
use crate::destination::mongodb_docker::{MongoDBDocker, DEFAULT_MONGO_CONTAINER_PORT};
use crate::destination::mysql_docker::{
    MysqlDocker, DEFAULT_MYSQL_CONTAINER_PORT, DEFAULT_MYSQL_IMAGE_TAG,
};
use crate::destination::postgres_docker::{
    PostgresDocker, DEFAULT_POSTGRES_CONTAINER_PORT, DEFAULT_POSTGRES_DB,
    DEFAULT_POSTGRES_IMAGE_TAG, DEFAULT_POSTGRES
    
pub fn list(datastore: &mut Box<dyn Datastore>) -> Result<(), Error> {
    let mut index_file = datastore.index_file()?;

    if index_file.dumps.is_empty() {
        println!("<empty> no dumps available\n");
        return Ok(());
    }

    index_file.dumps.sort_by(|a, b| a.cmp(b).reverse());

    let mut table = table();
    table.set_titles(row!["name", "size", "when", "compressed", "encrypted"]);
    let formatter = Formatter::new();
    let now = epoch_millis();

    for dump in index_file.dumps {
        table.add_row(row![
            dump.directory_name.as_str(),
            to_human_readable_unit(dump.size),
            formatter.convert(Duration::from_millis((now - dump.created_at) as u64)),
            dump.compressed,
            dump.encrypted,
        ]);
    }

    let _ = table.printstd();

    Ok(())
