        ArcEntry::File(name, data) => { /* do something */ }
        ArcEntry::Directory(name) => { /* do something else */ }
    }
}

Create a zip archive with a directory and a file:

use cra::{ArcWriter, ArcEntry, ArcFormat};

let mut writer = ArcWriter::new(Format::Zip);

writer.push(ArcEntry::Directory(String::from("some_dir")));
writer.push(ArcEntry::File(String::from("some_file"), data));

let finished_archive = writer.archive().unwrap(); // Vec<u8>
