StackRunning Out of Range

[brittle berry]

public struct MyStack 
{
    
    public NativeArray<int> stack;
    int count;
    public MyStack(int size)
    {
       stack = new NativeArray<int>(size,Allocator.Persistent);
        count = 0;
        
    }
    #region methods
    public void EnQueue(int item)
    {
        
        stack[count] = item;
        count++;
       
    }
    public int DeQueue()
    {
        
        count--;
        return stack[count];
    }
    #endregion
}

I wrote this code for my stack, but it keeps on running out of range, can somoene give me advice on how I can find the source of the issue?
That s the second script, which works in pairs with the stack

You're not doing any range checking here

[brittle berry]

yes

[scarlet drift]

What's to stop you from going out of range

[brittle berry]

because it s not supposed to run out of range

[scarlet drift]

It depends on the size you allocate vs how much you enqueue

[brittle berry]

yes that s why I posted my code, but my innitial question is that if Im not using additional threads is it possible that the copiler messes up some numbers because the list is constantly changing?

[scarlet drift]

No?

What list?

[brittle berry]

the stack, my struct it s a native array

[scarlet drift]

You probably should use a NativeList so it can resize
