Macro new_cache 

macro_rules! new_cache {
    () => { ... };
    ($slice:expr) => { ... };
}

Macro to create the cache, optionally including local valid files.

This includes the following:

• *.deb or *.ddeb files
• Packages and Sources files from apt repositories. These files can be compressed.
• *.dsc or *.changes files
• A valid directory containing the file ./debian/control

Here is an example of the two ways you can use this.

use rust_apt::new_cache;

let cache = new_cache!().unwrap();

println!("{}", cache.get("apt").unwrap().name());

// Any file that can be added to the cache
let local_files = vec![
    "tests/files/cache/apt.deb",
    "tests/files/cache/Packages",
];

let cache = new_cache!(&local_files).unwrap();
println!("{}", cache.get("apt").unwrap().get_version("5000:1.0.0").unwrap().version());

Returns Result<rust_apt::cache::Cache, rust_apt::error::AptErrors>
