    Ok({
        let source: &str = "file.1";
        let source: String = String::from(source);

        let destination: &str = "file.2";
        let destination: String = String::from(destination);

        file_access::write_string(&source, &"Hello, World!")?;
        file_access::rename(&source, &destination)?;

        // Clean-up:
        file_access::delete(&destination)?;
    })
