Thanks @XiangpengHao -- can you please add this benchmark to the existing cast kernel benchmarks rather than its own bench: https://github.com/apache/arrow-rs/blob/master/arrow/benches/cast_kernels.rs ?

(🤔 maybe we should move that cast_kernels.rs benchmark to arrow-cast/benchmarks )

Done.

The cast_kernel.rs can't be moved to arrow-cast/benches because it depends create_primitive_array and seedable_rng which are currently in arrow directory.

🚀

Merging this in so we can compare performace of main to the specialized cast kernels
