Struct FixedSizeBinaryBuilderWrapper 

pub struct FixedSizeBinaryBuilderWrapper { /* private fields */ }

Builder for Arrow FixedSizeBinary arrays (FIXED8, FIXED12, FIXED16).

Implementations

impl FixedSizeBinaryBuilderWrapper

pub fn new(capacity: usize, byte_width: i32) -> Self

Create a new fixed-size binary builder.

Arguments

• capacity - Number of fixed-size binary values to pre-allocate
• byte_width - Size of each binary value in bytes

Trait Implementations

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>
