# MTLFunctionOptions

Options that define how Metal compiles a GPU function.

```
struct MTLFunctionOptions
```

## Topics

### Function compilation options

[`MTLFunctionOptionNone`](/documentation/Metal/MTLFunctionOptions/MTLFunctionOptionNone)

A sentinel value that represents an empty set of options, which is the default behavior for creating functions.

[`failOnBinaryArchiveMiss`](/documentation/Metal/MTLFunctionOptions/failOnBinaryArchiveMiss)

An option that instructs the compiler to return an error when a GPU function isn’t in a binary archive.

[`compileToBinary`](/documentation/Metal/MTLFunctionOptions/compileToBinary)

An option that instructs the compiler to generate a binary format for dynamic linking.

[`pipelineIndependent`](/documentation/Metal/MTLFunctionOptions/pipelineIndependent)

An option that generates the same function handle across all pipeline states that link a function, which lets you share function tables across pipeline states.

[`storeFunctionInMetalPipelinesScript`](/documentation/Metal/MTLFunctionOptions/storeFunctionInMetalPipelinesScript)

An option that instructs the compiler to store function information for inspecting binary archives.

[`storeFunctionInMetalScript`](/documentation/Metal/MTLFunctionOptions/storeFunctionInMetalScript)

An option that instructs the compiler to store function information for inspecting binary archives.

### Swift support

[`init(rawValue:)`](/documentation/Metal/MTLFunctionOptions/init(rawValue:))

Creates a new function options structure from a raw value.
