Implementations

impl IndexStore

pub fn open(sift_dir: &Path) -> Result<Self>

Open an existing store at sift_dir.

Errors

Returns an error if CURRENT exists but cannot be read.

pub fn open_or_create( sift_dir: &Path, root: &Path, corpus_kind: CorpusKind, follow_links: bool, indexes: &[IndexKind], ) -> Result<Self>

Open an existing store or create a new one at sift_dir.

Errors

Returns an error if the store directory cannot be created or metadata cannot be written.

pub fn current_id(&self) -> Option<&str>

pub fn snapshot_dir(&self, id: &str) -> PathBuf

pub fn build( &mut self, kinds: &[IndexKind], config: &IndexConfig<'_>, ) -> Result<String>

Build a new snapshot using the given index kinds.

Returns the snapshot id.

Errors

Returns an error if the index build fails, the manifest cannot be written, or snapshot commit fails.

pub fn update( &mut self, kinds: &[IndexKind], config: &IndexConfig<'_>, ) -> Result<Option<String>>

Update the current snapshot, rebuilding only indexes whose corpus changed.

Returns the snapshot id if a new snapshot was published, or None if no index changed.

Errors

Returns an error if the current snapshot cannot be opened, the update check fails, or publishing the new snapshot fails.

pub fn open_current(&self) -> Result<Vec<Index>>

Open all indexes in the current snapshot.

Returns an empty vector if no snapshot exists.
