Implementations

impl PackageDatabase

pub fn new(db_path: &str) -> Self

pub fn load(&mut self) -> Result<(), KernelError>

Load database from VFS.

If the database file does not exist or the VFS is not available, the in-memory database remains empty – this is not an error.

pub fn save(&self) -> Result<(), KernelError>

Save database to VFS.

Creates parent directories if needed. Silently succeeds if the VFS is not available (early boot).

pub fn record_install(&mut self, record: DbPackageRecord)

Record a package installation.

pub fn record_remove(&mut self, name: &str) -> Option<DbPackageRecord>

Record a package removal.

Returns the removed record so the caller can log or undo it.

pub fn query_installed(&self) -> Vec<&DbPackageRecord>

Query all installed packages.

pub fn is_installed(&self, name: &str) -> bool

Check if a package is installed.

pub fn get(&self, name: &str) -> Option<&DbPackageRecord>

Get a package record by name.

pub fn is_dirty(&self) -> bool

Return whether the database has unsaved changes.

pub fn track_config_file(&mut self, package: &str, config: ConfigRecord)

Record a configuration file for a package.

pub fn is_config_modified(&self, package: &str, path: &str) -> bool

Check whether a config file has been modified by the user.

pub fn list_config_files(&self, package: &str) -> &[ConfigRecord]

List all tracked config files for a package.

pub fn find_orphans(&self) -> Vec<String>

Find orphan packages (packages with zero reverse dependencies).

A package is an orphan if no other installed package depends on it.
