Trait CompareKernel 

Source 
pub trait CompareKernel: VTable {
    // Required method
    fn compare(
        lhs: &Self::Array,
        rhs: &dyn Array,
        operator: Operator,
        ctx: &mut ExecutionCtx,
    ) -> VortexResult<Option<ArrayRef>>;
}
Expand description

Trait for encoding-specific comparison kernels that operate in encoded space.

Implementations can compare an encoded array against another array (typically a constant) without first decompressing. The adaptor normalizes operand order so array is always the left-hand side, swapping the operator when necessary.

Required Methods§

Source

fn compare( lhs: &Self::Array, rhs: &dyn Array, operator: Operator, 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", so this trait is not object safe.
