# FileWrapperDocumentReader

A document reader that uses FileWrapper for reading.

## Declaration

```swift
struct FileWrapperDocumentReader<Snapshot>
```

## Overview

Overview Use FileWrapperDocumentReader for simple cases where the application does not need custom reading logic. It is efficient for documents of small and medium size. note: For large files or packages, provide a custom DocumentReader that reads only what changed.
