Struct Inventory 

pub struct Inventory { /* private fields */ }

A snapshot of the machine’s packages.

Implementations

impl Inventory

pub fn gather(platform: &LinuxInfo) -> Self

Read this machine.

pub fn gather_for(manager: Option<PackageManager>) -> Self

Read this machine, whose packages manager keeps.

pub fn from_parts( manager: Option<PackageManager>, native: Option<HashMap<String, String>>, native_updates: HashMap<String, String>, flatpaks: HashMap<String, String>, flatpak_updates: HashSet<String>, ) -> Self

An inventory from known facts, for tests.

pub fn with_owners(self, owners: HashMap<PathBuf, String>) -> Self

The same, with which package owns each file fixed, for tests.

pub fn holds(&self, probe: &Probe) -> bool

Whether a probe holds, answered from the snapshot where it can be, and by asking the machine where it cannot (families not read).

pub fn version(&self, probe: &Probe) -> Option<String>

A package’s installed version, when the snapshot has it.

pub fn plan_update<'a>( &self, entries: impl IntoIterator<Item = &'a Entry>, platform: &LinuxInfo, on_path: &dyn Fn(&str) -> Option<PathBuf>, ) -> Plan

Plan updating entries: each package with a newer version through its own package manager or Flatpak, and on Arch one update of the whole system for all of them, since pacman does not support updating one package alone. Entries with nothing to update become notes.

pub fn status( &self, entry: &Entry, platform: &LinuxInfo, on_path: &dyn Fn(&str) -> Option<PathBuf>, ) -> Option<Status>

How a package entry stands; None for other entries.

pub fn owner(&self, path: &Path) -> Option<(PackageManager, String)>

The package of this machine’s manager that owns a file.
