Struct LabelScan 

pub struct LabelScan<'a> { /* private fields */ }

Scans all slots for a given label_id, reading specified columns.

Each call to next_chunk() returns one chunk containing one VectorGroup with all rows for the label (for simplicity in Phase 4; chunked in Phase 5+).

Implementations

impl<'a> LabelScan<'a>

pub fn new(store: &'a NodeStore, label_id: u32, col_ids: &[u32]) -> Self

Trait Implementations

impl<'a> Operator for LabelScan<'a>

fn next_chunk(&mut self) -> Result<Option<FactorizedChunk>>

fn collect_all(&mut self) -> Result<Vec<FactorizedChunk>>

Drain all chunks and materialize as a Vec.
