impl CastKernel for RLEVTable

fn cast( &self, array: &RLEArray, dtype: &DType, ) -> VortexResult<Option<ArrayRef>>

impl Debug for RLEVTable

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

Formats the value using the given formatter.

impl EncodeVTable<RLEVTable> for RLEVTable

fn encode( _vtable: &RLEVTable, canonical: &Canonical, _like: Option<&RLEArray>, ) -> VortexResult<Option<RLEArray>>

Try to encode a canonical array into this encoding.

impl OperationsVTable<RLEVTable> for RLEVTable

fn slice(array: &RLEArray, range: Range<usize>) -> ArrayRef

Perform a constant-time slice of the array.

fn scalar_at(array: &RLEArray, index: usize) -> Scalar

impl VTable for RLEVTable

type Array = RLEArray

type Metadata = ProstMetadata<RLEMetadata>

type ArrayVTable = RLEVTable

type CanonicalVTable = RLEVTable

type OperationsVTable = RLEVTable

type ValidityVTable = ValidityVTableFromChildSliceHelper

type VisitorVTable = RLEVTable

type ComputeVTable = NotSupported

Optionally enable implementing dynamic compute dispatch for this encoding. Can be disabled by assigning to the NotSupported type.

type EncodeVTable = RLEVTable

Optionally enable the EncodeVTable for this encoding. This allows it to partake in compression. Can be disabled by assigning to the NotSupported type.

fn id(&self) -> ArrayId

Returns the ID of the encoding.

fn encoding(_array: &Self::Array) -> ArrayVTable

Returns the encoding for the array.

fn with_children( array: &mut Self::Array, children: Vec<ArrayRef>, ) -> VortexResult<()>

Replaces the children in array with children. The count must be the same and types of children must be expected.

fn metadata(array: &RLEArray) -> VortexResult<Self::Metadata>

Exports metadata for an array.

fn serialize(metadata: Self::Metadata) -> VortexResult<Option<Vec<u8>>>

Serialize metadata into a byte buffer for IPC or file storage. Return None if the array cannot be serialized.

Deserialize metadata from a byte buffer.

fn build( &self, dtype: &DType, len: usize, metadata: &Self::Metadata, _buffers: &[BufferHandle], children: &dyn ArrayChildren, ) -> VortexResult<RLEArray>

Build an array from components.

fn execute( array: &Self::Array, ctx: &mut ExecutionCtx, ) -> Result<Vector, VortexError>

fn execute_parent( array: &Self::Array, parent: &Arc<dyn Array>, child_idx: usize, ctx: &mut ExecutionCtx, ) -> Result<Option<Vector>, VortexError>

Attempt to execute the parent of this array to produce a Vector.

fn reduce(array: &Self::Array) -> Result<Option<Arc<dyn Array>>, VortexError>

Attempt to reduce the array to a more simple representation.

fn reduce_parent( array: &Self::Array, parent: &Arc<dyn Array>, child_idx: usize, ) -> Result<Option<Arc<dyn Array>>, VortexError>

Attempt to perform a reduction of the parent of this array.
