# PhysicsResultEnumerable<T, TFilter>

> A lazy, allocation-free view over a physics result array that yields only the elements a filter keeps.

## Definition

* **Type:** Struct
* **Namespace:** [Unity.U2D.Physics](/engine/6000.7/script-reference/unity/u2d/physics.md)
* **Assembly:** UnityEngine.PhysicsCore2DModule

```csharp
public readonly ref struct PhysicsResultEnumerable<T, TFilter> where T : unmanaged where TFilter : IPhysicsResultFilter<T>
```

## Remarks

This is a ref struct so it cannot escape to the heap, which keeps the enumeration Burst-compatible. It does not own the source array and never disposes it, so disposal stays with whoever created the results.
