# IGH_QuickCast interface

Namespace: [Grasshopper.Kernel.Types](https://developer.rhino3d.com/api/gh1/namespace/grasshopper.kernel.types.md) · Assembly: [Grasshopper](https://developer.rhino3d.com/api/gh1/assembly/grasshopper.md)

```cs
public interface IGH_QuickCast
```

IGH_QuickCast allows certain components to speed up type detection for inputs. This interface is a Grasshopper core interface only, do not implement it. Do not use it.
