Struct PositionStream 

pub struct PositionStream { /* private fields */ }

Zero-copy reader of one term’s position stream.

Implementations

impl PositionStream

pub fn is_stream(raw: &[u8]) -> bool

Whether raw ends with a current position-stream footer.

pub fn open(bytes: OwnedBytes) -> Result<Self>

pub fn total_positions(&self) -> u64

pub fn num_blocks(&self) -> usize

pub fn decode_block(&self, idx: usize, out: &mut Vec<u32>) -> bool

Decode block idx (raw delta values) into out.

pub fn read_into( &self, cursor: u64, tf: u32, scratch: &mut Vec<u32>, out: &mut Vec<u32>, ) -> bool

Positions of one document: the tf values starting at cursor, delta-decoded into absolute positions. scratch reuses allocation.

Not for the query path: every call builds a fresh block cache, so consecutive documents in the same block are decoded again each time. Query iterators bind a TermPositionCursor (via TermPositions::into_cursor) which keeps the last decoded block.

pub fn concatenate_streaming<W: Write>( sources: &[&[u8]], writer: &mut W, ) -> Result<(u64, u64)>

Concatenate current-format streams by copying encoded blocks verbatim. Only the compact block index and footer are rebuilt.

Performs copy-assignment from source.

impl Debug for PositionStream

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