Kyle Strand commented on ARROW-6718:
------------------------------------

There is now a portable-SIMD Rust language working group: https://blog.rust-lang.org/inside-rust/2020/09/29/Portable-SIMD-PG.html

Their goal is to make "a portable SIMD API available to stable Rust users." We should follow their progress and adopt their recommendations.
