Code inspection: Shared static type parameter requires the unmanaged constraint

This inspection reports uses of SharedStatic<T> where T is not unmanaged.

SharedStatic<T> is intended for unmanaged data. If the type argument contains a managed field such as object, string, a class reference, or another managed member, this inspection warns on the GetOrCreate call.

Example

In this example, the SharedValue struct contains an object field, making it a managed type. It cannot be used as a type argument for SharedStatic<T>.

                using Unity.Burst;

                public struct SharedValue
                {
                    public int count;
                    public object tag;
                }

                public class Example
                {
                    private void Create()
                    {
                        // Reported: SharedValue is not unmanaged
                        var value = SharedStatic<SharedValue>.GetOrCreate<int>();
                    }
                }
            

                using Unity.Burst;

                public struct SharedValue
                {
                    public int count;
                    public double tag;
                }

                public class Example
                {
                    private void Create()
                    {
                        // Correct: SharedValue is fully unmanaged
                        var value = SharedStatic<SharedValue>.GetOrCreate<int>();
                    }
                }
            

Quick-fix

This inspection does not provide a dedicated quick-fix. Fix it manually by making the SharedStatic<T> type argument fully unmanaged.
