Struct fapt::system::System

pub struct System { /* fields omitted */ }

The core object, tying together configuration, caching, and listing.

Methods

impl System

pub fn cache_only() -> Result<Self, Error>

Produce a System with no configuration, using the user's cache directory.

pub fn cache_only_in<P: AsRef<Path>>(lists_dir: P) -> Result<Self, Error>

Produce a System with no configuration, using a specified cache directory.

pub fn add_sources_entries<I: IntoIterator<Item = Entry>>(&mut self, entries: I)

Add prepared sources entries.

These can be acquired from crate::sources_list. It is not recommended that you build them by hand.

pub fn set_arches<S: ToString, I: IntoIterator<Item = S>>(&mut self, arches: I)

Configure the architectures this system is using.

The first architecture is the "primary" architecture.

pub fn set_dpkg_database<P: AsRef<Path>>(&mut self, dpkg: P)

Configure the location of the dpkg database.

This can be used to view status information, i.e. information on currently installed packages.

pub fn add_keys_from<R: Read>(&mut self, source: R) -> Result<(), Error>

Load GPG keys from an old-style keyring (i.e. not a keybox file).

Note that this will reject invalid keyring files, unlike other *apt implementations.

pub fn update(&self) -> Result<(), Error>

Download any necessary Listings for the configured Sources Entries.

pub fn listings(&self) -> Result<Vec<DownloadedList>, Error>

Explain the configured Listings.

pub fn open_listing(
    &self,
    list: &DownloadedList
) -> Result<ListingBlocks, Error>

Open a DownloadedList, to access the packages inside it.

pub fn open_status(&self) -> Result<ListingBlocks, Error>

Open the dpkg status database, to access the packages inside it.
