Enum AgentNotification 

#[non_exhaustive]
pub enum AgentNotification {
    SessionNotification(SessionNotification),
    ExtNotification(ExtNotification),
}

All possible notifications that an agent can send to a client.

This enum is used internally for routing RPC notifications. You typically won’t need to use this directly - use the notification methods on the [Client] trait instead.

Notifications do not expect a response.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SessionNotification(SessionNotification)

Handles session update notifications from the agent.

This is a notification endpoint (no response expected) that receives real-time updates about session progress, including message chunks, tool calls, and execution plans.

Note: Clients SHOULD continue accepting tool call updates even after sending a session/cancel notification, as the agent may send final updates before responding with the cancelled stop reason.

See protocol docs: Agent Reports Output

ExtNotification(ExtNotification)

Handles extension notifications from the agent.

Allows the Agent to send an arbitrary notification that is not part of the ACP spec. Extension notifications provide a way to send one-way messages for custom functionality while maintaining protocol compatibility.

See protocol docs: Extensibility
