Struct tantivy::collector::DocSetCollector
source · [−]pub struct DocSetCollector;
Expand description
Collectors that returns the set of DocAddress that matches the query.
This collector is mostly useful for tests.
Trait Implementations
sourceimpl Collector for DocSetCollector
impl Collector for DocSetCollector
type Fruit = HashSet<DocAddress, RandomState>
type Fruit = HashSet<DocAddress, RandomState>
Fruit
is the type for the result of our collection.
e.g. usize
for the Count
collector. Read more
type Child = DocSetChildCollector
type Child = DocSetChildCollector
Type of the SegmentCollector
associated to this collector.
sourcefn for_segment(
&self,
segment_local_id: SegmentOrdinal,
_segment: &SegmentReader
) -> Result<Self::Child>
fn for_segment(
&self,
segment_local_id: SegmentOrdinal,
_segment: &SegmentReader
) -> Result<Self::Child>
set_segment
is called before beginning to enumerate
on this segment. Read more
sourcefn requires_scoring(&self) -> bool
fn requires_scoring(&self) -> bool
Returns true iff the collector requires to compute scores for documents.
sourcefn merge_fruits(
&self,
segment_fruits: Vec<(u32, HashSet<DocId>)>
) -> Result<Self::Fruit>
fn merge_fruits(
&self,
segment_fruits: Vec<(u32, HashSet<DocId>)>
) -> Result<Self::Fruit>
Combines the fruit associated to the collection of each segments into one fruit. Read more
