Google CityHash algorithm converted to C++11 constexpr functions so it can be called at compile time.
Currently supports only CityHash64 with strings up to 64 characters. Also provides a one argument version of CityHash64 that can take string literals: CityHash64("Hi")
#include "constexpr_cityhash.hpp"
#include <iostream>
using constexpr_cityhash::CityHash64;
template< uint64_t I >
struct id
{
static const uint64_t value = I;
};
int main(int argc, char* argv[])
{
id<CityHash64("Hello World")> i;
std::cout << i.value << "\n";
}
