Struct OpenIndex 

pub struct OpenIndex {
    pub content: ContentReader,
    pub trigrams: TrigramIndex,
    /* private fields */
}

Everything a query needs from the index, opened once.

Fields

content: ContentReader

Memory-mapped content.bin.

trigrams: TrigramIndex

Memory-mapped trigrams.bin (or an in-memory rebuild when the file is absent).

Implementations

impl OpenIndex

pub fn fingerprints( &self, cache: &CacheManager, ) -> Result<Arc<HashMap<String, FileFingerprint>>>

The fingerprint table, read once per handle.

pub fn meta_conn(&self) -> Result<MutexGuard<'_, Connection>>

The shared meta.db connection, opened on first use.

Lives as long as this handle, which is invalidated whenever the index files change on disk or an index run finishes, so it never outlives the index it was opened against. WAL readers coexist with a running indexer, and open_meta_db sets the busy timeout.

pub fn file_count(&self) -> usize

Number of files in the index.

pub fn file_id_for(&self, path: &str) -> Option<u32>

Array file id for a path as stored in the index (a leading ./ is ignored).

pub fn path_of(&self, file_id: u32) -> Option<&str>

Path for an array file id, without a leading ./.

pub fn pool(&self) -> &ThreadPool

The query-side thread pool, built on first use.

pub fn posting_cap(&self) -> usize

max_posting_list_entries the index was configured with (0 = unlimited).

pub fn cache_dir(&self) -> &Path

The cache directory this handle was opened from.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
