Implementations§
source§impl ColumnIndex
impl ColumnIndex
sourcepub fn get_cardinality(&self) -> Cardinality
pub fn get_cardinality(&self) -> Cardinality
Returns the cardinality of the column index.
By convention, if the column contains no docs, we consider that it is full.
sourcepub fn has_value(&self, doc_id: DocId) -> bool
pub fn has_value(&self, doc_id: DocId) -> bool
Returns true if and only if there are at least one value associated to the row.
pub fn value_row_ids(&self, doc_id: DocId) -> Range<RowId>
sourcepub fn docids_to_rowids(
&self,
doc_ids: &[DocId],
doc_ids_out: &mut Vec<DocId>,
row_ids: &mut Vec<RowId>
)
pub fn docids_to_rowids( &self, doc_ids: &[DocId], doc_ids_out: &mut Vec<DocId>, row_ids: &mut Vec<RowId> )
Translates a block of docis to row_ids.
returns the row_ids and the matching docids on the same index e.g. DocId In: [0, 5, 6] DocId Out: [0, 0, 6, 6] RowId Out: [0, 1, 2, 3]
pub fn docid_range_to_rowids(&self, doc_id_range: Range<DocId>) -> Range<RowId>
pub fn select_batch_in_place( &self, doc_id_start: DocId, rank_ids: &mut Vec<RowId> )
