Implementations

impl LexaDb

pub fn open( path: impl AsRef<Path>, embedding_config: EmbeddingConfig, ) -> Result<Self>

pub fn path(&self) -> &Path

pub fn embedder(&self) -> Result<&Mutex<Embedder>>

pub fn reranker(&self) -> Result<&Mutex<Reranker>>

pub fn index_path(&mut self, path: impl AsRef<Path>) -> Result<usize>

pub fn index_path_with_preprocessor<P>( &mut self, path: impl AsRef<Path>, preprocessor: Option<&dyn Preprocessor<Payload = P>>, commit_sidecar: impl Fn(&Transaction<'_>, i64, &P) -> Result<()>, ) -> Result<usize>

where P: Default,

Index a path with a per-file preprocessor and sidecar commit hook.

preprocessor is invoked for every supported file before chunking; it receives the raw bytes and may return Some(PreprocessedDoc) to substitute the text used for chunking (e.g. strip Obsidian frontmatter so it doesn’t leak into the embedding) along with a caller-defined payload of metadata. Returning None skips the file. Returning the unmodified text + Default::default() payload matches the plain index_path behaviour.

commit_sidecar runs inside the same transaction as the chunk inserts, so the caller’s sidecar tables (e.g. note_metadata, note_links, note_tags) stay consistent with documents even on crash.

pub fn purge_path(&mut self, path: impl AsRef<Path>) -> Result<usize>

pub fn search(&self, options: &SearchOptions) -> Result<Vec<SearchHit>>

pub fn conn(&self) -> &Connection

Borrow the underlying SQLite connection. Useful for crates that extend the schema (e.g. lexa-obsidian adds note_metadata, note_links, note_tags, note_blocks sidecar tables) and need to run their own SQL on the same connection rather than opening a second one (which would lock the WAL).

pub fn list_documents(&self) -> Result<Vec<Document>>

pub fn stats(&self) -> Result<IndexStats>
