Struct TextMessageContentEvent 

pub struct TextMessageContentEvent {
    pub base: BaseEvent,
    pub message_id: MessageId,
    pub delta: String,
}

Event containing a piece of text message content.

This event is sent for each chunk of content as the agent generates a message. The delta field contains the new text to append to the message.

Validation

The delta must not be empty. Use new() which returns a Result to validate, or new_unchecked() if you’ve already validated the input.

Fields

base: BaseEvent

Common event fields (timestamp, rawEvent).

message_id: MessageId

The message ID this content belongs to.

delta: String

The text content delta to append.

Implementations

impl TextMessageContentEvent

pub fn new( message_id: impl Into<MessageId>, delta: impl Into<String>, ) -> Result<Self, EventValidationError>

Creates a new TextMessageContentEvent with validation.

Returns an error if delta is empty.

pub fn new_unchecked( message_id: impl Into<MessageId>, delta: impl Into<String>, ) -> Self

Creates a new TextMessageContentEvent without validation.

Use this only if you’ve already validated the delta is not empty.

pub fn validate(&self) -> Result<(), EventValidationError>

Validates this event’s data.

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

Sets the timestamp for this event.

Trait Implementations

impl Clone for TextMessageContentEvent

fn clone(&self) -> TextMessageContentEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextMessageContentEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TextMessageContentEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TextMessageContentEvent

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
