Implementations

impl<T: PartialOrd + Default> Column<T>

pub fn build_empty_column(num_docs: u32) -> Column<T>

impl<T: MonotonicallyMappableToU64> Column<T>

pub fn to_u64_monotonic(self) -> Column<u64>

impl<T: PartialOrd + Copy + Debug + Send + Sync + 'static> Column<T>

pub fn get_cardinality(&self) -> Cardinality

pub fn num_docs(&self) -> RowId

pub fn min_value(&self) -> T

pub fn max_value(&self) -> T

pub fn first(&self, row_id: RowId) -> Option<T>

pub fn first_vals(&self, docids: &[DocId], output: &mut [Option<T>])

Load the first value for each docid in the provided slice.

pub fn row_ids_for_docs( &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 values_for_doc(&self, doc_id: DocId) -> impl Iterator<Item = T> + '_

pub fn get_docids_for_value_range( &self, value_range: RangeInclusive<T>, selected_docid_range: Range<u32>, doc_ids: &mut Vec<u32>, )

Get the docids of values which are in the provided value range.

pub fn fill_vals(&self, row_id: RowId, output: &mut Vec<T>)

Fills the output vector with the (possibly multiple values that are associated_with row_id.

This method clears the output vector.

pub fn first_or_default_col(self, default_value: T) -> Arc<dyn ColumnValues<T>>
