simd-csv

There are already a quite a few [0][1] CSV parsers that use SIMD, some in Rust, with a variety of approaches. I found simd-csv[1] to have a very interesting approach that leverages memchr to essentially "seek" for the next delimiter, reducing a lot of the overhead that a byte-by-byte CSV parser would have. However, as noted in the README, the creators of simd-csv explicitly chose not to use the classic pclmulqdq trick[2] that other libraries like simdjson use due to portability concerns. I set out to beat to simd-csv's implementation by building a parser more similar to Geoff Langdale's, using the pclmulqdq trick as well as optimized intrinsic usage for aarch64 platforms[3]. If anyone has feedback on the Rust code, or my usage of intrinsics, I would greatly appreciate it. [0] https://github.com/geofflangdale/simdcsv [1] https://github.com

Nice! Funny coincidence, @Yomguithereal has been working for the past few weeks pretty much on the same idea of using SIMD for CSV parsing, but in Rust! https://github.com/medialab/simd-csv
