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: render_readmes.rs
    path of file: ./repos/crates.io/src/admin
    
    the code of the file until where you have to start completion: use crate::{
    db,
    models::Version,
    schema::{crates, readme_renderings, versions},
};
use anyhow::{anyhow, Context};
use std::path::PathBuf;
use std::{io::Read, path::Path, sync::Arc, thread};

use crate::storage::Storage;
use chrono::{NaiveDateTime, Utc};
use crates_io_markdown::text_to_html;
use crates_io_tarball::{Manifest, StringOrBool};
use diesel::prelude::*;
use flate2::read::GzDecoder;
us
    
    fn test_render_pkg_readme_w_link() {
        let serialized_archive = TarballBuilder::new()
            .add_file(
                "foo-0.0.1/Cargo.toml",
                br#"
[package]
name = "foo"
version = "0.0.1"
readme = "README.md"
repository = "https://github.com/foo/foo"
"#,
            )
            .add_file("foo-0.0.1/README.md", b"readme [link](./Other.md)")
            .build_unzipped();

        let result =
            render_pkg_readme(tar::Archive::new(&*serialized_archive), "foo-0.0.1").unwrap();
        assert!(result.contains("\"https://github.com/foo/foo/blob/HEAD/./Other.md\""))
    }
