A serializable HashSet<> for serializable type, SerializedReference type & interface type. Duplicated element will have a warning color.

If the type is an interface or an abstract class, the polymorphism picker will be used.

You can use SaintsHashSet attribute to control paging & searching

Parameters:

• bool searchable = true: false to disable the search function
• int numberOfItemsPerPage = 0: how many items per page. 0 for no paging

public SaintsHashSet<string> stringHashSet;  // default

[SaintsHashSet(numberOfItemsPerPage: 5)]  // paging control
public SaintsHashSet<int> integerHashSet = new SaintsHashSet<int>
{
    1, 2, 3, 4, 5, 6, 7, 8, 9, 0,
};

public interface IReference
{
    string Name { get; }
}

// ... implement of IReference omited here

public SaintsHashSet<IReference> refHashSet;

Example of using on interface where you can pick either Unity Object or serializable class/struct:

ReferenceHashSet is used if you want to pick a polymorphism type (while the type itself is not abstract)

[Serializable]
public class Sub1 : BaseC
{
    public string sub1;
}

[Serializable]
public class Sub2 : Sub1
{
    public string sub2;
}

// SaintsHashSet will treat it as a serializable type
public SaintsHashSet<Sub1> noPolymorphism;
// ReferenceHashSet will treat it as a reference type, allows you to pick polymorphism types
public ReferenceHashSet<Sub1> polymorphism;
