Struct BitPackedArray 

pub struct BitPackedArray<T: ArrowPrimitiveType>
where
    T::Native: BitPacking,
{ /* private fields */ }

A bit-packed array.

Implementations

impl<T: ArrowPrimitiveType> BitPackedArray<T>

where T::Native: BitPacking,

pub fn new_null_array(len: usize) -> Self

Creates a new null array with the given length.

pub fn from_primitive(array: PrimitiveArray<T>, bit_width: NonZero<u8>) -> Self

Creates a new bit-packed array from a primitive array and a bit width.

pub fn to_primitive(&self) -> PrimitiveArray<T>

Converts the bit-packed array to a primitive array.

pub fn get_array_memory_size(&self) -> usize

Returns the memory size of the bit-packed array.

pub fn to_bytes(&self, buffer: &mut Vec<u8>)

pub fn from_bytes(bytes: Bytes) -> Self

where T::Native: BitPacking,

Deserializes a bit-packed array from a byte buffer.

Trait Implementations

impl<T: ArrowPrimitiveType> Clone for BitPackedArray<T>

where T::Native: BitPacking,

Implement Clone for any T that implements ArrowPrimitiveType and BitPacking This allows us to clone it without requiring T to implement Clone

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug + ArrowPrimitiveType> Debug for BitPackedArray<T>

where T::Native: BitPacking + Debug,

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

Formats the value using the given formatter.
