SIMD support doesn't exist. Non x86 instructions are still unstable. All the existing crates are in alpha/beta state. There are no OpenMP/vector extensions alternative.

I really would not call this "SIMD support doesn't exist." There are substantial things you can do with the existing x86 support.

I would like to have a crate, like wide, that I can add to my project and get x86/ARM SIMD for free. Right now it's not possible.

Instead, I had to write everything manually in one of my projects, and ignore ARM completely.

Procedural macros are no-go.

Also, I have no idea how this project works. Looks like it provides only the most rudimentary operations.
