HashOf(Types const&... values);absl::HashOf() is a helper that generates a hash from the values of its arguments. It dispatches to absl::Hash directly, as follows: * HashOf(t) == absl::Hash<T>{}(t) * HashOf(a, b, c) == HashOf(std::make_tuple(a, b, c))
HashOf(a1, a2, ...) == HashOf(b1, b2, ...) is guaranteed when * The argument lists have pairwise identical C++ types * a1 == b1 && a2 == b2 && ...
The requirement that the arguments match in both type and value is critical. It means that a == b does not necessarily imply HashOf(a) == HashOf(b) if a and b have different types. For example, HashOf(2) != HashOf(2.0).
The combined hash of the arguments.
