# Transcript.DataEntry

A top-level transcript entry payload in a serialized, portable format.

## Declaration

```swift
struct DataEntry
```

## Overview

Overview A Transcript.DataEntry records the bytes and identifier of a value that a LanguageModel implementation opted into via supportsDataEntryType(_:). It’s what a DataEntryRepresentable-conforming type produces from its transcriptRepresentation, and it round-trips through the transcript’s Codable conformance so the transcript remains portable even in environments where the declaring package isn’t installed.
