You can use https://github.com/simd-everywhere/simde if you like. In general portable SIMD libraries are of limited utility because having different primitives available on different architectures often means that you should approach problems differently. That is to say, in many cases using any portable SIMD API to solve your problem means leaving 200% speedups on the table on at least one of your top 3 targets.
The thing that is present in Zig and not yet stable in Rust does not include any dynamic shuffles, so these end up requiring intrinsics or asm for all sorts of things. It's a significant weakness compared to e.g. highway, eve, or simde.
