Struct PostingListReader 

pub struct PostingListReader<'a> { /* private fields */ }

Iterates over a posting list, yielding (DocId, term_frequency) pairs.

Handles both the original format and the position-aware format. When reading position-aware data, positions are skipped automatically.

Implementations

impl<'a> PostingListReader<'a>

pub fn new(data: &'a [u8]) -> Self

Create a reader from encoded posting list bytes.

Handles both the original format (no positions) and the position-aware format (with flags byte). When reading position-aware data, positions are skipped — only doc_id and tf are returned. Use PositionPostingListReader to read positions.

pub fn len(&self) -> u32

Number of postings in this list.

pub fn is_empty(&self) -> bool

Whether the posting list is empty.

pub fn next(&mut self) -> Option<(DocId, u32)>

Read the next (DocId, tf) pair, or None if exhausted. If the underlying data has positions, they are skipped.
