Struct tantivy::query::Intersection

pub struct Intersection<TDocSet: DocSet> { /* fields omitted */ }

Creates a DocSet that iterator through the intersection of two DocSets.

Methods

impl<TDocSet: DocSet> Intersection<TDocSet>

Important traits for &'a mut [u8]

impl<'a> Write for &'a mut [u8]impl<'a> Read for &'a [u8]

pub fn docsets(&self) -> &[TDocSet]

Returns an array to the underlying DocSets of the intersection. These DocSet are in the same position as the IntersectionDocSet, so that user can access their docfreq and positions.

Trait Implementations

impl<TDocSet: DocSet> From<Vec<TDocSet>> for Intersection<TDocSet>

fn from(docsets: Vec<TDocSet>) -> Intersection<TDocSet>

Performs the conversion.

impl<TDocSet: DocSet> DocSet for Intersection<TDocSet>

fn advance(&mut self) -> bool

Goes to the next element. .advance(...) needs to be called a first time to point to the correct element.

fn skip_next(&mut self, target: DocId) -> SkipResult

After skipping, position the iterator in such a way that .doc() will return a value greater than or equal to target.

fn doc(&self) -> DocId

Returns the current document

fn size_hint(&self) -> u32

Returns a best-effort hint of the length of the docset.

fn fill_buffer(&mut self, buffer: &mut [DocId]) -> usize

Fills a given mutable buffer with the next doc ids from the DocSet

fn append_to_bitset(&mut self, bitset: &mut BitSet)

Appends all docs to a bitset.

fn count(&mut self) -> u32

Returns the number documents matching.

impl<TScorer> Scorer for Intersection<TScorer> where
    TScorer: Scorer, 

fn score(&mut self) -> Score

Returns the score.

fn collect(&mut self, collector: &mut Collector)

Consumes the complete DocSet and push the scored documents to the collector.
