Data

@Serializable

data class Data(val type: String, val data: JsonElement, val providerMetadata: Map<String, JsonElement>? = null, val id: String? = null, val transient: Boolean = false) : UIMessagePart

Typed custom data part. Mirrors v6 data-* UI parts while using an explicit type string instead of TypeScript literal keys.

Constructors

Data

constructor(type: String, data: JsonElement, providerMetadata: Map<String, JsonElement>? = null, id: String? = null, transient: Boolean = false)

Properties

data

val data: JsonElement

val id: String?

Optional stable id. Streaming data parts that share an id replace the prior one in place (e.g. a progress indicator that updates) rather than appending a duplicate — matching v6's keyed data parts.

providerMetadata

val providerMetadata: Map<String, JsonElement>?

transient

val transient: Boolean

Transient parts are shown live but not meant to be persisted in stored message history. Mirrors v6's transient data-chunk flag.

type

val type: String

Functions

dataAs

inline fun <TData> UIMessagePart.Data.dataAs(): TData
