Struct Indexes 

pub struct Indexes { /* private fields */ }

Registry of opened indexes read from a snapshot store.

Opens all index kinds found in the current snapshot and provides query-time candidate narrowing by intersecting results from each index. Multiple indexes together produce tighter narrowing than any single index alone.

Owns a [Snapshot] that holds a reader lease, preventing the snapshot from being garbage-collected while searches are active.

Implementations

impl Indexes

pub fn from_single(index: Index, root: PathBuf) -> Self

Create an Indexes registry from a single index and its root.

Useful for testing and benchmarking.

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

Open all indexes found under sift_dir.

Errors

Returns IndexError::InvalidManifest if a snapshot manifest is malformed, or IndexError::Trigram if a trigram index is malformed.

Returns an empty registry if no current snapshot exists (walk fallback).

pub const fn is_empty(&self) -> bool

pub fn root(&self) -> &Path

pub fn candidates(&self, query: &QuerySpec<'_>) -> Option<Vec<Candidate>>

Produce narrowed candidates from all indexes that can narrow the query.

Returns None if no index could narrow. When at least one index narrows, all narrowed candidate sets are intersected.

pub fn indexed_rel_paths(&self) -> HashSet<PathBuf>

Corpus-relative paths present in the current snapshot.

pub fn unindexed_hits( &self, hits: impl IntoIterator<Item = PathBuf>, ) -> Vec<PathBuf>

Corpus-relative search hits not yet present in the current snapshot.

pub fn first(&self) -> Option<&Index>

pub fn corpus_kind(&self) -> Option<CorpusKind>
