# failOnBinaryArchiveMiss

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

## Declaration

```swift
static var failOnBinaryArchiveMiss: MTLFunctionOptions { get }
```

## Discussion

Discussion By default, Metal compiles a function if it isn’t in a binary archive. When you set this option, Metal returns an error instead of compiling a missing function. Setting this option is a way to verify that binary archives contain all the functions your app needs, or to measure a binary archive’s hit rates.
