Struct AsyncStoreReader 

pub struct AsyncStoreReader { /* private fields */ }

Async document store reader - loads blocks on demand

Implementations

impl AsyncStoreReader

pub async fn open(file_handle: FileHandle, cache_blocks: usize) -> Result<Self>

Open a document store from FileHandle Only loads footer and index into memory, data blocks are fetched on-demand

pub fn num_docs(&self) -> u32

Number of documents

pub fn cached_blocks(&self) -> usize

Number of blocks currently in the cache

pub async fn get( &self, doc_id: DocId, schema: &Schema, ) -> Result<Option<Document>>

Get a document by doc_id (async - may load block)

pub async fn get_fields( &self, doc_id: DocId, schema: &Schema, field_ids: &[u32], ) -> Result<Option<Document>>

Get specific fields of a document by doc_id (async - may load block)

Only deserializes the requested fields, skipping over unwanted data. Much faster than get() when documents have large fields (text bodies, vectors) that aren’t needed for the response.

impl AsyncStoreReader

pub fn raw_blocks(&self) -> Vec<RawStoreBlock>

Get raw block metadata for merging (without loading block data)

pub fn data_slice(&self) -> &FileHandle

Get the data slice for raw block access

pub fn has_dict(&self) -> bool

Check if this store uses a dictionary (incompatible with raw merging)

pub fn dict(&self) -> Option<&CompressionDict>

Get the decompression dictionary (if any)
