Somewhat related, does rust handle the riscv vector extension in a similar way to simd?

Scalable vectors as in RVV & SVE aren't available in rust corrently; see https://github.com/rust-lang/rust/issues/145052

(that said autovectorization should work, and fixed-width SIMD should map to RVV as best as possible, though of course missing out on perf if ran on wider-than-minimum hardware not on a native build)
