Komihash is a hash function passes all smhasher tests with extremely
high performance. A PRNG named komirand is also provided that passes
PractRand test. See the original C implementation for more details.
This crate archives almost the same performance with the original C implementation. The benchmark is done on an Apple Macbook Pro (Apple M1 Pro).
