Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
pthash
- Fast and compact minimal perfect hash functions in C++
-
announcing ph - open-source, rust library for perfect hashing
The best in terms of evaluation time is PTHash (I think it can achieve 1 cache miss/lookup). Unfortunately the only implementation I know of for this method is in C++ (there is certainly no implementation in Rust): https://github.com/jermp/pthash
komihash
- Streamed Hashing Added to Komihash 4.6. Very Fast Hash Function (in C), competitor to xxhash, wyhash. Java port available.
- komihash 4.4 released - a very fast hash function (competitor to xxhash, wyhash), C
- Komirand (64-bit C) - Simple, reliable, self-starting, fast (0.73 cycles/byte) PRNG with 2^64 period. Spin-off from Komihash.
- Komihash – Fast Hash Function
- Very Fast Non-Cryptographic Hash Function (competitor to wyhash, xxhash), C
- Komihash – Very Fast Hash Function (competitor to wyhash, xxhash)
