Trait Implementations

impl BufferBuilderTrait<BooleanType> for BufferBuilder<BooleanType>

fn new(capacity: usize) -> Self

Creates a builder with a fixed initial capacity.

fn advance(&mut self, i: usize) -> Result<()>

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

Appends a value into the builder, growing the internal buffer as needed.

fn append_slice(&mut self, slice: &[bool]) -> Result<()>

Appends a slice of type T, growing the internal buffer as needed.

fn reserve(&mut self, n: usize) -> Result<()>

Reserves memory for n elements of type T.

fn finish(&mut self) -> Buffer

Reset this builder and returns an immutable Buffer.

fn len(&self) -> usize

fn capacity(&self) -> usize

impl ArrowPrimitiveType for BooleanType

type Native = bool

fn get_data_type() -> DataType

Returns the corresponding Arrow data type of this primitive type.

fn get_bit_width() -> usize

Returns the bit width of this primitive type.

fn default_value() -> Self::Native

Returns a default value of this primitive type.
