# ByteCountFormatStyle.Attributed

A format style that converts byte counts into attributed strings.

## Declaration

```swift
struct Attributed
```

## Overview

Overview Use the attributed modifier on a ByteCountFormatStyle to create a format style of this type. The attributed strings that this fomat style creates contain attributes from the AttributeScopes.FoundationAttributes.NumberFormatAttributes attribute scope. Use these attributes to determine which runs of the attributed string represent different parts of the formatted value.
