Module arrow::compute::kernels::comparison[−][src]

Expand description

Defines basic comparison kernels for PrimitiveArrays.

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.

Functions

contains	Checks if a `GenericListArray` contains a value in the `PrimitiveArray`
contains_utf8	Checks if a `GenericListArray` contains a value in the `GenericStringArray`
eq	Perform `left == right` operation on two arrays.
eq_scalar	Perform `left == right` operation on an array and a scalar value.
eq_utf8	Perform `left == right` operation on `StringArray` / `LargeStringArray`.
eq_utf8_scalar	Perform `left == right` operation on `StringArray` / `LargeStringArray` and a scalar.
gt	Perform `left > right` operation on two arrays. Non-null values are greater than null values.
gt_eq	Perform `left >= right` operation on two arrays. Non-null values are greater than null values.
gt_eq_scalar	Perform `left >= right` operation on an array and a scalar value. Non-null values are greater than null values.
gt_eq_utf8	Perform `left >= right` operation on `StringArray` / `LargeStringArray`.
gt_eq_utf8_scalar	Perform `left >= right` operation on `StringArray` / `LargeStringArray` and a scalar.
gt_scalar	Perform `left > right` operation on an array and a scalar value. Non-null values are greater than null values.
gt_utf8	Perform `left > right` operation on `StringArray` / `LargeStringArray`.
