Struct TextMessageChunkEvent 

pub struct TextMessageChunkEvent {
    pub base: BaseEvent,
    pub message_id: Option<MessageId>,
    pub role: Option<TextMessageRole>,
    pub delta: Option<String>,
    pub name: Option<String>,
    pub subagent_run_id: Option<SubagentRunId>,
}

A self-contained text update: start, content and end folded into one event.

Producers that cannot bracket a message use this; consumers expand a run of chunks sharing a message_id into the equivalent start/content/end triple.

Fields

base: BaseEvent

Timestamp and raw provider event.

message_id: Option<MessageId>

The message this chunk belongs to.

role: Option<TextMessageRole>

Who is speaking.

delta: Option<String>

The text to append.

name: Option<String>

Display name for the author.

subagent_run_id: Option<SubagentRunId>

The subagent that produced this event; absent means the parent agent. A JSON null is rejected — see crate::event::subagent. Under concurrency a chunk that omits its message_id is resolved within the sending subagent’s own stream, so attribute every chunk when several subagents stream at once.

Implementations

impl TextMessageChunkEvent

pub fn new(message_id: Option<MessageId>, delta: Option<String>) -> Self

Builds a chunk carrying a message id and a text delta.

Trait Implementations

impl Clone for TextMessageChunkEvent

fn clone(&self) -> TextMessageChunkEvent

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ComposeSchema for TextMessageChunkEvent

fn compose(generics: Vec<RefOr<Schema>>) -> RefOr<Schema>

impl Debug for TextMessageChunkEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TextMessageChunkEvent

fn default() -> TextMessageChunkEvent

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TextMessageChunkEvent

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<TextMessageChunkEvent> for Event

fn from(payload: TextMessageChunkEvent) -> Self

Converts to this type from the input type.

impl JsonSchema for TextMessageChunkEvent

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for TextMessageChunkEvent

fn eq(&self, other: &TextMessageChunkEvent) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TextMessageChunkEvent

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for TextMessageChunkEvent

impl ToSchema for TextMessageChunkEvent

fn name() -> Cow<'static, str>

Return name of the schema.

fn schemas(schemas: &mut Vec<(String, RefOr<Schema>)>)

Implement reference [utoipa::openapi::schema::Schema]s for this type.
