Module cmp 

Comparison kernels for Arrays.

These kernels can leverage SIMD if available on your system. Currently no runtime detection is provided, you should enable the specific SIMD intrinsics using RUSTFLAGS="-C target-feature=+avx2" for example. See the documentation here for more information.

Structs

ReeInfo 🔒

Run-end encoding metadata for one side of a comparison. Holds a reference to the original REE array for deferred typed access to run_ends.

SideInfo 🔒

Per-side metadata for a comparison operand.

Enums

Op 🔒

Traits

ArrayOrd 🔒

Functions

apply 🔒

Perform a potentially vectored op on the provided ArrayOrd

apply_op 🔒

Applies op to possibly scalar ArrayOrd

apply_op_ree_segments 🔒

Compare two REE arrays by walking both run_ends simultaneously, comparing once per aligned segment and bulk-filling the result.

apply_op_vectored 🔒

Applies op to possibly scalar ArrayOrd with the given indices

apply_ree 🔒

Dispatch op for a REE-vs-REE comparison (no dictionary on either side) using segment-based bulk comparison.

collect_bool 🔒

Invokes f with values 0..len collecting the boolean results into a new BooleanBuffer

compare_byte_view

Compares two [GenericByteViewArray] at index left_idx and right_idx

compare_op 🔒

Perform op on the provided Datum

distinct

Perform left IS DISTINCT FROM right operation on two [Datum]

eq

Perform left == right operation on two [Datum].

expand_from_runs 🔒

Expand a physical-length BooleanBuffer to logical length by bulk-appending each run’s result. Zero allocation — downcasts internally to access typed run_ends directly.

gt

Perform left > right operation on two [Datum].

gt_eq

Perform left >= right operation on two [Datum].

logical_indices 🔒

Build a logical→physical index vector for one side of a non-scalar comparison.

lt

Perform left < right operation on two [Datum].

lt_eq

Perform left <= right operation on two [Datum].

neq

Perform left != right operation on two [Datum].

not_distinct

Perform left IS NOT DISTINCT FROM right operation on two [Datum]

ree_info_opt 🔒

If array is RunEndEncoded, return its physical values array and run metadata.

ree_physical_indices 🔒

scalar_index 🔒

supports_distinct 🔒

Returns true if distinct (via compare_op) can handle this data type.

take_bits 🔒
