# setUniformTransform(type:transform:)

Registers a raw-data transformer closure for a uniform of type V.

## Declaration

```swift
func setUniformTransform<V>(type: V.Type, transform: @escaping @_lifetime(0: copy 0) (inout MutableRawSpan, Entity) -> Void) where V : BitwiseCopyable
```

## Parameters

- `type`: The BitwiseCopyable type the transformer operates on.
- `transform`: A closure (inout MutableRawSpan, Entity) -> Void.

## Discussion

Discussion Use this overload when the transformation is most naturally expressed over the raw byte representation of the value.
