pub struct XmlBatchBuilder { /* private fields */ }

Builds Arrow batches from complete XML record elements.

Implementations

impl XmlBatchBuilder

pub fn new(schema: XmlSchema, batch_size: usize) -> Result<Self>

Creates a builder with a positive row limit.

pub fn new_projected( schema: XmlSchema, batch_size: usize, projection: &[usize], ) -> Result<Self>

Selects columns in order; duplicate or invalid indices fail. Only selected fields are converted; an empty projection counts rows. XML syntax is always checked.

pub fn append_xml(&mut self, input: &str) -> Result<()>

Appends a complete XML record. Errors leave pending rows unchanged.

pub fn len(&self) -> usize

Pending row count.

pub fn is_empty(&self) -> bool

Whether the batch is empty.

pub fn is_full(&self) -> bool

Whether the row limit has been reached.

pub fn schema(&self) -> SchemaRef

Projected output schema.

pub fn flush(&mut self) -> Result<Option<RecordBatch>>

Flushes pending rows; returns None if empty.
