In case someone finds it interesting, kernel bypass also exposes hardware capabilities which can be used for optimization. A recent research attempts at leveraging NICs to accelerate data serialization https://www.sigops.org/s/conferences/hotos/2021/papers/hotos...

It is interesting to note how it compares to "choose" (also in Rust) in the benchmarks.
single character
hck 1.494 ± 0.026s
hck (no-mmap) 1.735 ± 0.004s
choose 4.597 ± 0.016s
hck 2.127 ± 0.004s
hck (no-mmap) 2.467 ± 0.012s
choose 3.266 ± 0.011s
Of course, doing away with a pass is suppossed to give 2x, and I am wondering whether the regex constraint lead to this "side-effect".
