Struct LiquidFloatArray 

pub struct LiquidFloatArray<T: LiquidFloatType> { /* private fields */ }

An array that stores floats in ALP

Implementations

impl<T> LiquidFloatArray<T>

where T: LiquidFloatType,

pub fn is_empty(&self) -> bool

Check if the Liquid float array is empty.

pub fn len(&self) -> usize

Get the length of the Liquid float array.

pub fn get_array_memory_size(&self) -> usize

Get the memory size of the Liquid primitive array.

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

Create a Liquid primitive array from an Arrow float array.

pub fn squeeze_policy(&self) -> FloatSqueezePolicy

Get current squeeze policy for this array

impl<T> LiquidFloatArray<T>

where T: LiquidFloatType,

pub fn from_bytes(bytes: Bytes) -> Self

Deserialize a LiquidFloatArray from bytes, using zero-copy where possible.

Trait Implementations

impl<T: Clone + LiquidFloatType> Clone for LiquidFloatArray<T>

where T::UnsignedIntType: Clone, T::Native: Clone, T::SignedIntType: Clone,

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + LiquidFloatType> Debug for LiquidFloatArray<T>

where T::UnsignedIntType: Debug, T::Native: Debug, T::SignedIntType: Debug,

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

Formats the value using the given formatter.

impl<T> LiquidArray for LiquidFloatArray<T>

where T: LiquidFloatType,

fn as_any(&self) -> &dyn Any

Get the underlying any type.

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 to_arrow_array(&self) -> ArrayRef

Convert the Liquid array to an Arrow array.

fn original_arrow_data_type(&self) -> DataType

Get the original arrow data type of the Liquid array.

fn data_type(&self) -> LiquidDataType

Get the logical data type of the Liquid array.

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

Serialize the Liquid array to a byte array.

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.

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 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.
