Struct FlatDataWrapper 

pub struct FlatDataWrapper { /* private fields */ }

Wrapper to treat a flat DataChunk as FactorizedData.

This enables uniform handling of flat and factorized data in operators.

Implementations

impl FlatDataWrapper

pub fn new(chunk: DataChunk) -> Self

Creates a new wrapper around a flat DataChunk.

pub fn into_inner(self) -> DataChunk

Returns the underlying DataChunk.

Trait Implementations

impl FactorizedData for FlatDataWrapper

fn chunk_state(&self) -> &ChunkState

Returns the chunk state (factorization status, cached data).

fn logical_row_count(&self) -> usize

Returns the logical row count (considering selection).

fn physical_size(&self) -> usize

Returns the physical size (actual stored values).

fn is_factorized(&self) -> bool

Returns true if this data is factorized (multi-level).

fn flatten(&self) -> DataChunk

Flattens to a DataChunk (materializes if factorized).

fn as_factorized(&self) -> Option<&FactorizedChunk>

Returns as FactorizedChunk if factorized, None if flat.

fn as_flat(&self) -> Option<&DataChunk>

Returns as DataChunk if flat, None if factorized.
