for entry in archive {
    match entry {
        ArcEntry::File(name, data) => { /* do something */ }

Create a zip archive with a directory and a file:

``` rust
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>
```
