Struct tantivy::postings::IntersectionDocSet

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

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

Methods

impl<TDocSet: DocSet> IntersectionDocSet<TDocSet>

Important traits for &'a [u8]

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

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

Performs the conversion.

impl<TDocSet: DocSet> DocSet for IntersectionDocSet<TDocSet>

fn size_hint(&self) -> u32

Returns the minimum .size_hint() of the intersected docsets.

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 doc(&self) -> DocId

Returns the current document

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

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

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

Advances the cursor to the next document None is returned if the iterator has DocSet has already been entirely consumed.

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

Appends all docs to a bitset.
