Header-only constexpr and consteval implementations of common non-cryptographic hash functions.
Right now, this library only includes Google's Cityhash. If you study the code, you can quickly see that it is virtually the same compared to Google's.
The code is written for C++23 because it uses std::byteswap.
This is first and foremost a personal library, and some stuff in there is really quick-and-dirty.
- Convert to module instead of header
- Add consteval overloads
- Clean up visibility and make only the right functions visible to outside callers
- Clean up tests
