# maximumXattrSizeInBits

The maximum extended attribute size in bits.

## Declaration

```swift
optional var maximumXattrSizeInBits: Int { get }
```

## Discussion

Discussion Implement at least one of maximumXattrSize or maximumXattrSizeInBits. FSKit automatically converts from one to another if needed. If you implement both, FSKit uses only the maximumXattrSizeInBits implementation.
