Struct RowBatch 

pub struct RowBatch { /* private fields */ }

A batch of rows for efficient processing.

Row batches allow vectorized operations on multiple rows at once.

Implementations

impl RowBatch

pub fn new(schema: Arc<Schema>) -> Self

Creates a new row batch.

pub fn with_rows(schema: Arc<Schema>, rows: Vec<Row>) -> Self

Creates a row batch with the given rows.

pub fn schema(&self) -> &Schema

Returns the schema.

pub fn schema_arc(&self) -> Arc<Schema>

Returns the shared schema reference.

pub fn rows(&self) -> &[Row]

Returns the rows in this batch.

pub fn len(&self) -> usize

Returns the number of rows.

pub fn is_empty(&self) -> bool

Returns true if the batch is empty.

pub fn push(&mut self, row: Row)

Adds a row to the batch.

pub fn pop(&mut self) -> Option<Row>

Removes and returns the last row.

pub fn clear(&mut self)

Clears the batch.

pub fn into_rows(self) -> Vec<Row>

Consumes the batch and returns the rows.
