Trait ListContainsElementKernel 

Source 
pub trait ListContainsElementKernel: VTable {
    // Required method
    fn list_contains(
        list: &ArrayRef,
        element: ArrayView<'_, Self>,
        options: &ListContainsOptions,
        ctx: &mut ExecutionCtx,
    ) -> VortexResult<Option<ArrayRef>>;
}
Expand description

Check list-contains, potentially reading buffers.

Like ListContainsElementReduce, this dispatches on the element (needle) child at index 1. Unlike the reduce variant, implementations may read and execute on buffers via the provided ExecutionCtx.

The list of an optimized node is a PreparedSet, so a kernel can get the prepared set with PreparedSet::set_of and look up its own values with PreparedSetData::contains or PreparedSetData::contains_scalar, or make its result from matches it found another way with PreparedSetData::result_from_bits.

Required Methods§

Source

fn list_contains( list: &ArrayRef, element: ArrayView<'_, Self>, options: &ListContainsOptions, ctx: &mut ExecutionCtx, ) -> VortexResult<Option<ArrayRef>>

Dyn Compatibility§

This trait is not dyn compatible.

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