Trait TakeExecute 

pub trait TakeExecute: VTable {
    // Required method
    fn take(
        array: ArrayView<'_, Self>,
        indices: &ArrayRef,
        ctx: &mut ExecutionCtx,
    ) -> VortexResult<Option<ArrayRef>>;
}

Required Methods

fn take( array: ArrayView<'_, Self>, indices: &ArrayRef, ctx: &mut ExecutionCtx, ) -> VortexResult<Option<ArrayRef>>

Take elements from an array at the given indices, potentially reading buffers.

Unlike TakeReduce, this trait is for take implementations that may need to read and execute on the underlying buffers to produce the result.

Preconditions

The indices are guaranteed to be non-empty.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl TakeExecute for Bool

impl TakeExecute for Chunked

impl TakeExecute for Decimal

impl TakeExecute for Dict

impl TakeExecute for Extension

impl TakeExecute for Filter

impl TakeExecute for FixedSizeList

Take implementation for FixedSizeListArray.

FixedSizeListArray must rebuild its elements array because selected lists need to become packed from offset 0. The FSL layer translates selected list rows into ordered element runs and delegates the execution strategy to the elements child via PiecewiseSequenceArray indices.

impl TakeExecute for List

impl TakeExecute for ListView

Execution-path take for ListViewArray.

impl TakeExecute for Primitive
