GenerateKey()

template<typename IntType >

IntType boardstate::PseudoRandomKeyGenerator< IntType >::GenerateKey ( )

inline

Generates a pseudorandom IntType value using mt19937.

The 0xFFFFFFFF bit mask is used b/c std::mt19937 uses std::uint_fast32_t which is a 64-bit integer on 64-bit systems (but still only uses the lower 32 bits). See discussion at: https://stackoverflow.com/questions/63601328/why-do-std-implementations-of-mt19937-have-double-sizeof-as-boost-version
