Function apply_cmp_dict 

Source 
pub fn apply_cmp_dict<T: Integer + Hash>(
    lhs: CategoricalAVT<'_, T>,
    rhs: CategoricalAVT<'_, T>,
    op: ComparisonOperator,
) -> Result<BooleanArray<()>, KernelError>
Expand description

Applies comparison operations between corresponding categorical dictionary values.

Performs element-wise comparison by resolving both operands from their respective categorical dictionaries and comparing the resulting string values.

§Parameters

  • lhs: Left categorical array view tuple (CategoricalArray, offset, length)
  • rhs: Right categorical array view tuple (CategoricalArray, offset, length)
  • op: Comparison operator (Eq, Ne, Lt, Le, Gt, Ge, In, NotIn)

§Type Parameters

  • T: Integer type for categorical array indices (must implement Hash)

§Returns

Result<BooleanArray<()>, KernelError> where true elements satisfy the comparison.

§Performance

  • Dictionary lookups amortised across bulk categorical operations
  • Hash-based optimisations for set membership operations
  • Efficient categorical code comparison where possible
