Struct DirectBuildCompositeRow 

pub struct DirectBuildCompositeRow { /* private fields */ }

A direct-build composite row that owns the probe row directly.

This stores the probe Row directly without Arc wrapping, saving one Arc allocation per matched row. The build rows are shared via Arc for efficient access.

Implementations

impl DirectBuildCompositeRow

pub fn new( probe: Row, build_rows: CompactArc<Vec<Row>>, build_idx: usize, probe_is_left: bool, ) -> Self

Create a new direct-build composite row.

pub fn len(&self) -> usize

Get the total number of columns.

pub fn is_empty(&self) -> bool

Check if this row is empty.

pub fn get(&self, idx: usize) -> Option<&Value>

Get a value by index without cloning.

pub fn materialize(&self) -> Row

Materialize into an owned Row (cloning version).

pub fn materialize_owned(self) -> Row

Materialize into an owned Row by moving probe values.

Combines probe and build rows efficiently:

• Moves probe values (owned) - uses extend_into_compact_vec to avoid Vec allocation
• Clones build values (shared reference)
