pub struct AsyncStoreReader { /* private fields */ }Expand description
Async document store reader - loads blocks on demand
Implementations§
Source§impl AsyncStoreReader
impl AsyncStoreReader
Sourcepub async fn open(file_handle: FileHandle, cache_blocks: usize) -> Result<Self>
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
Sourcepub fn cached_blocks(&self) -> usize
pub fn cached_blocks(&self) -> usize
Number of blocks currently in the cache
Sourcepub async fn get(
&self,
doc_id: DocId,
schema: &Schema,
) -> Result<Option<Document>>
pub async fn get( &self, doc_id: DocId, schema: &Schema, ) -> Result<Option<Document>>
Get a document by doc_id (async - may load block)
Sourcepub async fn get_fields(
&self,
doc_id: DocId,
schema: &Schema,
field_ids: &[u32],
) -> Result<Option<Document>>
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.
Source§impl AsyncStoreReader
impl AsyncStoreReader
Sourcepub fn raw_blocks(&self) -> Vec<RawStoreBlock>
pub fn raw_blocks(&self) -> Vec<RawStoreBlock>
Get raw block metadata for merging (without loading block data)
Sourcepub fn data_slice(&self) -> &FileHandle
pub fn data_slice(&self) -> &FileHandle
Get the data slice for raw block access
Sourcepub fn has_dict(&self) -> bool
pub fn has_dict(&self) -> bool
Check if this store uses a dictionary (incompatible with raw merging)
Sourcepub fn dict(&self) -> Option<&CompressionDict>
pub fn dict(&self) -> Option<&CompressionDict>
Get the decompression dictionary (if any)
