Struct LargeBinaryBuilderWrapper 

pub struct LargeBinaryBuilderWrapper { /* private fields */ }

Builder for Arrow LargeBinary arrays (BLOB).

Supports eager materialization of BLOB LOB values with optional size limits to prevent OOM conditions.

Implementations

impl LargeBinaryBuilderWrapper

pub fn new(capacity: usize, data_capacity: usize) -> Self

Create a new large binary builder.

pub fn default_capacity() -> Self

Create with default capacities.

pub const fn with_max_lob_bytes(self, max: usize) -> Self

Set the maximum LOB size in bytes.

LOB values exceeding this size will cause an error during conversion.

Trait Implementations

impl Debug for LargeBinaryBuilderWrapper

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl HanaCompatibleBuilder for LargeBinaryBuilderWrapper

fn append_hana_value(&mut self, value: &HdbValue<'_>) -> Result<()>

Append a HANA value to this builder.

fn append_null(&mut self)

Append a null value to this builder.

fn finish(&mut self) -> ArrayRef

Finish building and return the Arrow array.

fn len(&self) -> usize

Returns the number of values (including nulls) appended so far.

fn capacity(&self) -> Option<usize>

Returns the capacity hint for this builder, if known.

fn reset(&mut self)

Reset the builder, clearing all data while preserving capacity.

fn is_empty(&self) -> bool

Returns true if no values have been appended.
