`memchr4` #148

Closed turalcar closed 3 months ago

turalcar commented 3 months ago

I found myself needing one. This was brought up several years ago in https://github.com/BurntSushi/memchr/issues/11 and https://github.com/BurntSushi/memchr/issues/38. I'm just wondering if anything changed since then.

Nothing has changed. Someone has to litigate the experiment. I am unlikely to do it myself any time soon. If someone wants support for memchr4, then they will need to:

Add it as a new routine.
Add support for it to the benchmark harness.
Do an analysis of how it compares versus the naive implementation of memchr4.
If the SIMD version is a measurably and ideally significant improvement over the naive version, then I'd probably be okay accepting it into the crate as a new API.
