Detailed Description

template<typename Derived>
struct tuple_hash::TupleHashOps< Derived >

Help for making your simple struct hashable. Provides a constructor that takes one argument for each member exposed through asTuple().

ex:

struct MyStruct : tuple_hash::TupleHashOps<MyStruct> { // be sure update the template parameter to the base class int i,j;

MyStruct(int i, int j) : i(i), j(j) { } // required until c++17 (inheriting precludes aggregate property) auto asTuple() const { return std::make_tuple(i,j); } // all you have to do is provide this function. Retuning std::tie is fine. };

std::unordered_map<MyStruct, int, MyStruct::Hash> myMap; mySet.emplace(MyStruct{1,1}, 1);
