A structure containing common layer parameters.

```
struct BNNSLayerData
```

## Topics

### Initializers

[`init()`](/documentation/Accelerate/BNNSLayerData/init())

[`init(data:data_type:data_scale:data_bias:data_table:)`](/documentation/Accelerate/BNNSLayerData/init(data:data_type:data_scale:data_bias:data_table:))

Returns a new layer data structure.

[`init(data:data_type:data_scale:data_bias:)`](/documentation/Accelerate/BNNSLayerData/init(data:data_type:data_scale:data_bias:))

### Instance Properties

[`data`](/documentation/Accelerate/BNNSLayerData/data)

Pointer to layer values (weights, bias), layout and size are specific to each layer.

[`data_bias`](/documentation/Accelerate/BNNSLayerData/data_bias)

Conversion bias for values, used for integer data types only, ignored for indexed and float data types.

[`data_scale`](/documentation/Accelerate/BNNSLayerData/data_scale)

Conversion scale for values, used for integer data types only, ignored for indexed and float data types.

[`data_table`](/documentation/Accelerate/BNNSLayerData/data_table)

Conversion table (256 values) for indexed floating point data, used for indexed data types only.

[`data_type`](/documentation/Accelerate/BNNSLayerData/data_type)

Storage data type for the values stored in data.
