Struct ActivityDeltaEvent 

pub struct ActivityDeltaEvent {
    pub base: BaseEvent,
    pub message_id: MessageId,
    pub activity_type: String,
    pub patch: Vec<JsonValue>,
}

Event containing an incremental activity update.

This event applies a JSON Patch (RFC 6902) to an existing activity’s content. Use this for efficient partial updates to activity content.

Example

use ag_ui_core::event::ActivityDeltaEvent;
use ag_ui_core::MessageId;
use serde_json::json;

let event = ActivityDeltaEvent::new(
    MessageId::random(),
    "PLAN",
    vec![json!({"op": "add", "path": "/steps/-", "value": "deploy"})],
);

Fields

base: BaseEvent

Common event fields (timestamp, rawEvent).

message_id: MessageId

The message ID for this activity.

activity_type: String

The type of activity (e.g., “PLAN”, “RESEARCH”).

patch: Vec<JsonValue>

JSON Patch operations (RFC 6902) to apply to the content.

Implementations

impl ActivityDeltaEvent

pub fn new( message_id: impl Into<MessageId>, activity_type: impl Into<String>, patch: Vec<JsonValue>, ) -> Self

Creates a new ActivityDeltaEvent with the given message ID, type, and patch.

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

Sets the timestamp for this event.

Trait Implementations

impl Clone for ActivityDeltaEvent

fn clone(&self) -> ActivityDeltaEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActivityDeltaEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ActivityDeltaEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ActivityDeltaEvent

fn eq(&self, other: &ActivityDeltaEvent) -> 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 ActivityDeltaEvent

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
