BlockPostingIterator

Struct BlockPostingIterator 

Source
pub struct BlockPostingIterator<'a> { /* private fields */ }
Expand description

Iterator over block posting list with skip support Can be either borrowed or owned via Cow

Document IDs and frequencies have separate bounded decode buffers. Document movement does not initialize frequencies; score and position consumers do. Only the current block is retained, including during scratch recycling.

Implementations§

Source§

impl<'a> BlockPostingIterator<'a>

Source

pub fn position_cursor(&self) -> u64

Offset of the current posting’s positions in the term’s position stream (see structures::postings::positions_v2): the block’s cursor plus the term frequencies of the postings before it in the block. Meaningful only for lists built with position cursors.

Source

pub fn doc(&self) -> DocId

Source

pub fn term_freq(&self) -> u32

Source

pub fn advance(&mut self) -> DocId

Source

pub fn seek(&mut self, target: DocId) -> DocId

Source

pub fn skip_to_next_block(&mut self) -> DocId

Skip to the next block, returning the first doc_id in the new block This is used for block-max pruning when the current block’s max score can’t beat the threshold.

Source

pub fn current_block_idx(&self) -> usize

Get the current block index

Source

pub fn num_blocks(&self) -> usize

Get total number of blocks

Source

pub fn current_block_max_tf(&self) -> u32

Get the current block’s max term frequency for block-max pruning
