Disclosure: I'm the author of the memchr crate.
You mention the memchr crate, but you don't seem to have benchmarked it. Instead, you benchmarked the needle crate (last updated 7 years ago). Can you explain a bit more about your methodology?
The memchr crate in particular doesn't just use Rabin-Karp. It also uses Two-Way. And SIMD (with support for x86-64, aarch64 and wasm32).
FYI: Not the author, just found it to be an interesting read. Notified the author, so lets hope he joins in for a nice discussion.
