Struct VecColumn

pub struct VecColumn<T = u64> { /* private fields */ }

VecColumn provides Column over a Vec<T>.

Trait Implementations

impl<T: Copy + PartialOrd + Send + Sync + Debug + 'static> ColumnValues<T> for VecColumn<T>

fn get_val(&self, position: u32) -> T

Return the value associated with the given idx.

fn iter(&self) -> Box<dyn Iterator<Item = T> + '_>

Returns a iterator over the data

fn min_value(&self) -> T

Returns a lower bound for this column of values.

fn max_value(&self) -> T

Returns an upper bound for this column of values.

fn num_vals(&self) -> u32

The number of values in the column.

fn get_range(&self, start: u64, output: &mut [T])

Fills an output buffer with the fast field values associated with the DocId going from start to start + output.len().

fn get_vals(&self, indexes: &[u32], output: &mut [T])

Allows to push down multiple fetch calls, to avoid dynamic dispatch overhead.

fn get_vals_opt(&self, indexes: &[u32], output: &mut [Option<T>])

Allows to push down multiple fetch calls, to avoid dynamic dispatch overhead. The slightly weird Option<T> in output allows pushdown to full columns.

fn get_row_ids_for_value_range( &self, value_range: RangeInclusive<T>, row_id_range: Range<RowId>, row_id_hits: &mut Vec<RowId>, )

Get the row ids of values which are in the provided value range.

impl<T: Copy + PartialOrd + Default> From<Vec<T>> for VecColumn<T>

fn from(values: Vec<T>) -> Self

Converts to this type from the input type.

impl From<VecColumn> for Vec<u64>

fn from(column: VecColumn) -> Self

Converts to this type from the input type.
