Struct LiquidPrimitiveDeltaArray 

pub struct LiquidPrimitiveDeltaArray<T: LiquidPrimitiveType> { /* private fields */ }

Check if the Liquid primitive delta array is empty.

pub fn from_arrow_array( arrow_array: PrimitiveArray<T>, ) -> LiquidPrimitiveDeltaArray<T>

Create a Liquid primitive delta array from an Arrow primitive array.

impl<T> LiquidPrimitiveDeltaArray<T>

pub fn from_bytes(bytes: Bytes) -> Self

Deserialize a LiquidPrimitiveDeltaArray from bytes

Trait Implementations

impl<T: Clone + LiquidPrimitiveType> Clone for LiquidPrimitiveDeltaArray<T>

where T::UnSignedType: Clone, T::Native: Clone,

fn clone(&self) -> LiquidPrimitiveDeltaArray<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + LiquidPrimitiveType> Debug for LiquidPrimitiveDeltaArray<T>

where T::UnSignedType: Debug, T::Native: Debug,

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

Formats the value using the given formatter.

impl<T> LiquidArray for LiquidPrimitiveDeltaArray<T>

where T: LiquidPrimitiveType + PrimitiveKind,

fn get_array_memory_size(&self) -> usize

Get the memory size of the Liquid array.

fn len(&self) -> usize

Get the length of the Liquid array.

fn original_arrow_data_type(&self) -> DataType

Get the original arrow data type of the Liquid array.

fn as_any(&self) -> &dyn Any

Get the underlying any type.

fn to_arrow_array(&self) -> ArrayRef

Convert the Liquid array to an Arrow array.

fn filter(&self, selection: &BooleanBuffer) -> ArrayRef

Filter the Liquid array with a boolean array and return an arrow array.

fn try_eval_predicate( &self, _predicate: &Arc<dyn PhysicalExpr>, _filter: &BooleanBuffer, ) -> Option<BooleanArray>

Try to evaluate a predicate on the Liquid array with a filter. Returns None if the predicate is not supported.

fn to_bytes(&self) -> Vec<u8>

Serialize the Liquid array to a byte array.

fn data_type(&self) -> LiquidDataType

Get the logical data type of the Liquid array.

fn squeeze( &self, _io: Arc<dyn SqueezeIoHandler>, _expression_hint: Option<&CacheExpression>, ) -> Option<(LiquidSqueezedArrayRef, Bytes)>

Squeeze the Liquid array to a LiquidHybridArrayRef and a bytes::Bytes. Return None if the Liquid array cannot be squeezed.

fn is_empty(&self) -> bool

Check if the Liquid array is empty.

fn to_best_arrow_array(&self) -> ArrayRef

Convert the Liquid array to an Arrow array. Except that it will pick the best encoding for the arrow array. Meaning that it may not obey the data type of the original arrow array.
