  • portable-simd

    The testing ground for the future of portable SIMD in Rust

    • The standard API crate for portable simd is at https://github.com/rust-lang/portable-simd, but using this requires nightly, which I don't want to do. I'd like to use a crate for simd that works on both x86_64 and wasm in stable rust. wide looks fine for this purpose. Are there any potentially better choices?

  • rust-memchr

    Optimized string search routines for Rust.

    • The memchr crate (for memmem) uses SIMD on both x86_64 and wasm, but does not use any external crate, works on stable and is capable of enabling SIMD usage at runtime instead of requiring special compilation flags to be used. It does this by defining its own little bespoke platform independent layer: https://github.com/BurntSushi/memchr/blob/8037d11b4357b0f07be2bb66dc2659d9cf28ad32/src/memmem/vector.rs
