void
hashAppend(
HASH_ALGORITHM& algorithm,
std::variant<TYPE...> const& input);Pass the index of the active variant of the specified input to the specified algorithm, followed by the active value itself, to be combined into the internal state of the algorithm that is used to produce the resulting hash value.
