Function `object.hashOf`

Calculates the hash value of arg with seed initial value. The result may not be equal to typeid(T).getHash(&arg). The seed value may be used for hash chaining:


						
				size_t hashOf(T)
				(
				

				  auto ref T arg,
				

				  size_t seed = 0
				

				);

struct Test
{
    int a;
    string b;
    MyObject c;

    size_t toHash() const @safe pure nothrow
    {
        size_t hash = a.hashOf();
        hash = b.hashOf(hash);
        size_t h1 = c.myMegaHash();
        hash = h1.hashOf(hash); //Mix two hash values
        return hash;
    }
}
