Struct arrow::array::LargeBinaryBuilder

pub struct LargeBinaryBuilder { /* fields omitted */ }

Implementations

impl LargeBinaryBuilder

pub fn new(capacity: usize) -> Self

Creates a new LargeBinaryBuilder, capacity is the number of bytes in the values array

pub fn append_byte(&mut self, value: u8) -> Result<()>

Appends a single byte value into the builder's values array.

Note, when appending individual byte values you must call append to delimit each distinct list value.

pub fn append_value(&mut self, value: &[u8]) -> Result<()>

Appends a byte slice into the builder.

Automatically calls the append method to delimit the slice appended in as a distinct array element.

pub fn append(&mut self, is_valid: bool) -> Result<()>

Finish the current variable-length list array slot.

pub fn append_null(&mut self) -> Result<()>

Append a null value to the array.

pub fn finish(&mut self) -> LargeBinaryArray

Builds the LargeBinaryArray and reset this builder.

Trait Implementations

impl ArrayBuilder for LargeBinaryBuilder

fn as_any(&self) -> &dyn Any

Returns the builder as a non-mutable Any reference.

fn as_any_mut(&mut self) -> &mut dyn Any

Returns the builder as a mutable Any reference.

fn append_data(&mut self, data: &[ArrayDataRef]) -> Result<()>

Appends data from other arrays into the builder

This is most useful when concatenating arrays of the same type into a builder.

fn data_type(&self) -> DataType

Returns the data type of the builder

This is used for validating array data types in append_data

fn into_box_any(self: Box<Self>) -> Box<dyn Any>

Returns the boxed builder as a box of Any.

fn len(&self) -> usize

Returns the number of array slots in the builder

fn is_empty(&self) -> bool

Returns whether the number of array slots is zero

fn finish(&mut self) -> ArrayRef

Builds the array and reset this builder.

impl Debug for LargeBinaryBuilder

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

Formats the value using the given formatter.
