source§fn doc(&self) -> DocId
fn doc(&self) -> DocId
Returns the current document
Right after creating a new
DocSet
, the docset points to the first document. Read moresource§fn count_including_deleted(&mut self) -> u32
fn count_including_deleted(&mut self) -> u32
Returns the count of documents, deleted or not.
Calling this method consumes the
DocSet
. Read moresource§fn fill_buffer(&mut self, buffer: &mut [DocId; 64]) -> usize
fn fill_buffer(&mut self, buffer: &mut [DocId; 64]) -> usize
Fills a given mutable buffer with the next doc ids from the
DocSet
Read moresource§fn count(&mut self, alive_bitset: &AliveBitSet) -> u32
fn count(&mut self, alive_bitset: &AliveBitSet) -> u32
Returns the number documents matching.
Calling this method consumes the
DocSet
