Trait BindCtx 

pub trait BindCtx {
    // Required method
    fn bind(
        &mut self,
        array: &ArrayRef,
        selection: Option<&ArrayRef>,
    ) -> VortexResult<BatchKernelRef>;
}

Context for binding batch execution kernels.

By binding child arrays through this context, we can perform common subtree elimination and share canonicalized results across multiple kernels.

Required Methods

fn bind( &mut self, array: &ArrayRef, selection: Option<&ArrayRef>, ) -> VortexResult<BatchKernelRef>

Bind the given array and optional selection to produce a batch kernel, possibly reusing previously bound results from this context.

Implementations

impl dyn BindCtx + '_

pub fn bind_selection( &mut self, mask_len: usize, mask: Option<&ArrayRef>, ) -> VortexResult<MaskExecution>

Bind an optional selection mask into a MaskExecution.

The caller must provide a mask length to handle the case where no mask is provided.

pub fn bind_mask(&mut self, mask: &ArrayRef) -> VortexResult<MaskExecution>

Bind a non-nullable boolean array into a MaskExecution.

This binding will optimize for constant arrays or other array types that can be more efficiently converted into a Mask.

impl dyn BindCtx + '_

pub fn bind_validity( &mut self, validity: &Validity, array_len: usize, selection: Option<&ArrayRef>, ) -> VortexResult<MaskExecution>

Bind a validity helper into a MaskExecution.

Implementations on Foreign Types

impl BindCtx for ()

fn bind( &mut self, array: &ArrayRef, selection: Option<&ArrayRef>, ) -> VortexResult<BatchKernelRef>
