> and is very limited You might be thinking of the `simd` crate, in which case, you're right. But we are getting closer and closer to exposing a large set of vendor intrinsics: https://github.com/rust-lang-nursery/stdsimd --- You can use it today on Rust nightly. This includes runtime CPU feature detection! ripgrep is an example of a program that is written in Rust, is CPU bound and uses explicit SIMD in various places to speed up text search. (It hasn't moved to stdsimd yet and is still using the `simd` crate and the old platform intrinsics system exposed by rustc. But ripgrep will move to stdsimd soonish.)
