# BNNSGraph.CompileOptions

The compilation options that BNNS uses when compiling a source mlmodelc file to a graph object.

```
struct CompileOptions
```

## Overview

Call `/Accelerate/BNNSGraph/Context/init(compileFromPath:functionName:options:)` to create a default options structure and then set properties such as [`optimizationPreference`](/documentation/Accelerate/BNNSGraph/CompileOptions/optimizationPreference-swift.property) to specify individual options.

## Topics

### Creating a compilation options structure

[`init()`](/documentation/Accelerate/BNNSGraph/CompileOptions/init())

Creates an allocated compilation-options object with default values.

[`init(useSingleThread: Bool, generateDebugInfo: Bool, optimizationPreference: BNNSGraph.CompileOptions.OptimizationPreference)`](/documentation/Accelerate/BNNSGraph/CompileOptions/init(useSingleThread:generateDebugInfo:optimizationPreference:))

Creates an allocated compilation-options object with the specified values.

### Specifying and querying compilation options

[`var useSingleThread: Bool`](/documentation/Accelerate/BNNSGraph/CompileOptions/useSingleThread)

A Boolean value that specifies whether the graph executes on one thread.

[`var generateDebugInfo: Bool`](/documentation/Accelerate/BNNSGraph/CompileOptions/generateDebugInfo)

A Boolean value that specifies whether the generated graph includes debug info.

[`var optimizationPreference: BNNSGraph.CompileOptions.OptimizationPreference`](/documentation/Accelerate/BNNSGraph/CompileOptions/optimizationPreference-swift.property)

A constant that specifies the graph compilation-optimization preferences.

### Specifying the optimization preference

[`struct OptimizationPreference`](/documentation/Accelerate/BNNSGraph/CompileOptions/OptimizationPreference-swift.struct)

Constants that describe the compilation-optimization preference.
