Adding a second value to a HashSet<(Vector2, Vector2)>breaks Odin editor.

[Eduardo Freire]

Adding a second value to a HashSet<(Vector2, Vector2)>breaks Odin editor.
with:

ArgumentException: At least one object must implement IComparable. 

Just create this class with and add two entries on the HashSet in Inspector (or by code)

public class HashSetTest : SerializedMonoBehaviour 
{ 
    [ShowInInspector] private HashSet<(Vector2, Vector2)> hashset;
} 

The problem occurs with (Vector2, Vector2), (Vector3, Vector3), (Quaternion, Quaternion). Tested with (int, int) and got no problems.

Also, this only occurs in Odin. Just not having the ShowInInspector (or not having the gameobject with this component selected/showing is enough to keep the exception from happening.

Create a BaseDictionaryKeyPathProvider<T> for your Tuple and register it using [assembly: Sirenix.Serialization.RegisterDictionaryKeyPathProvider(typeof(MyKeyPathProvider)].
