Struct tantivy::query::ConstScorer[−][src]

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

Expand description

Wraps a DocSet and simply returns a constant Scorer. The ConstScorer is useful if you have a DocSet where you needed a scorer.

The ConstScorer’s constant score can be set by calling .set_score(...).

Implementations

[src]

impl<TDocSet: DocSet> ConstScorer<TDocSet>

[src]

fn advance(&mut self) -> DocId

Goes to the next element. Read more

[src]

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

Advances the DocSet forward until reaching the target, or going to the lowest DocId greater than the target. Read more

[src]

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

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

[src]

fn doc(&self) -> DocId

Returns the current document Right after creating a new DocSet, the docset points to the first document. Read more

[src]

fn size_hint(&self) -> u32

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