how use Contains function for this?

[bbsuuo]

NativeHeap<int,Min> list= new NativeHeap<int, Min>(Allocator.Temp);
list.Insert(0);
list.Insert(3);
list.Insert(5);

bool contain = list.Contains(3) // need function like this

[bbsuuo]

add where T : unmanaged, IEquatable

and function
public bool Contains(T item)
{
unsafe
{
#if NHEAP_SAFE
AtomicSafetyHandle.CheckWriteAndThrow(m_Safety);
#endif
for (int i = 0; i < _data->Count; i++)
{
var node = ReadArrayElement(_data->Heap, i);
if (item.Equals(node.Item) )
{
return true;
}
}

        }
        return false;
    }

I did it on the spur of the moment and I don't know if it would be weird
