Struct tantivy::postings::SegmentPostings [−][src]
pub struct SegmentPostings { /* fields omitted */ }
Expand description
SegmentPostings
represents the inverted list or postings associated to
a term in a Segment
.
As we iterate through the SegmentPostings
, the frequencies are optionally decoded.
Positions on the other hand, are optionally entirely decoded upfront.
Implementations
Compute the number of non-deleted documents.
This method will clone and scan through the posting lists. (this is a rather expensive operation).
Trait Implementations
Advances the DocSet forward until reaching the target, or going to the lowest DocId greater than the target. Read more
Fills a given mutable buffer with the next doc ids from the
DocSet

Returns the number documents matching.
Calling this method consumes the DocSet
. Read more
Returns the count of documents, deleted or not.
Calling this method consumes the DocSet
. Read more
Returns the frequency associated to the current document. If the schema is set up so that no frequency have been encoded, this method should always return 1.
Panics
Will panics if called without having called advance before.
Returns the positions offseted with a given value.
The output vector will be resized to the term_freq
. Read more
