    • SIMD for faster calculations? #357

    we can use SIMD to improve calculations and math speed

    The compiler is already really well at using SIMD, if the code is well written. On the other hand, having some SIMD code as a tutorial for instruction-level parallelism in Rust would be awesome!

    We should keep in mind that the main focus of this repository is to give a pretty good implementation of some algos/DSs over having the best implementation by sacrificing readability or the educational aspect. If I were going to start reading OpenSSL's implementation of SHA-256, I would fail miserably. But it is arguably the most secure and performant implementation out there.

    TLDR; We always love to have educational and well-written code, no matter how advanced it might be. But having the best implementation out there is pretty much an anti-goal. Having said that, writing examples of SIMD hand-optimized code with good documentation can be both fun and educational!

    Feel free to add separate implementations that use SIMD instructions. They'll reside next to usual algorithms and indicate with their name how they are different from conventional/SISD versions of the same algorithm.
