Struct ActivitySnapshotEvent 

pub struct ActivitySnapshotEvent {
    pub base: BaseEvent,
    pub message_id: MessageId,
    pub activity_type: String,
    pub content: JsonValue,
    pub replace: Option<bool>,
}

Event containing a complete activity snapshot.

This event creates a new activity message or replaces an existing one. Activity messages track structured agent activities like planning or research.

Example

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

let event = ActivitySnapshotEvent::new(
    MessageId::random(),
    "PLAN",
    json!({"steps": ["research", "implement", "test"]}),
);

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”).

content: JsonValue

The activity content as a flexible JSON object.

replace: Option<bool>

Whether to replace the existing activity content (default: true).

Implementations

impl ActivitySnapshotEvent

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

Creates a new ActivitySnapshotEvent with the given message ID, type, and content.

pub fn with_replace(self, replace: bool) -> Self

Sets whether to replace the existing activity content.

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

Sets the timestamp for this event.

Trait Implementations

impl Clone for ActivitySnapshotEvent

fn clone(&self) -> ActivitySnapshotEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActivitySnapshotEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ActivitySnapshotEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ActivitySnapshotEvent

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
