Module arrow::compute::kernels::comparison

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
