# userFactorStorage

A Boolean value that indicates whether user-provided storage backs this object.

## Declaration

```swift
var userFactorStorage: Bool
```

## Discussion

Discussion If true, the user must free factor storage after all references finish (though SparseCleanup(_:) still frees any additional allocated storage due to pivoting).
