Struct TextMessageStartEvent 

pub struct TextMessageStartEvent {
    pub base: BaseEvent,
    pub message_id: MessageId,
    pub role: Role,
}

Event indicating the start of a text message.

This event is sent when the agent begins generating a text message. The message_id identifies this message throughout the streaming process.

Example

use ag_ui_core::{MessageId, Role};
use ag_ui_core::event::TextMessageStartEvent;

let event = TextMessageStartEvent::new(MessageId::random());
assert_eq!(event.role, Role::Assistant);

Fields

base: BaseEvent

Common event fields (timestamp, rawEvent).

message_id: MessageId

Unique identifier for this message.

role: Role

The role of the message sender (always Assistant for new messages).

Implementations

impl TextMessageStartEvent

pub fn new(message_id: impl Into<MessageId>) -> Self

Creates a new TextMessageStartEvent with the given message ID.

pub fn with_timestamp(self, timestamp: f64) -> Self

Sets the timestamp for this event.

pub fn with_raw_event(self, raw_event: JsonValue) -> Self

Sets the raw event for this event.

Trait Implementations

impl Clone for TextMessageStartEvent

fn clone(&self) -> TextMessageStartEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextMessageStartEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TextMessageStartEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TextMessageStartEvent

fn eq(&self, other: &TextMessageStartEvent) -> 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.

where __S: Serializer,

Serialize this value into the given Serde serializer.
