Enum ClientNotification 

#[non_exhaustive]
pub enum ClientNotification {
    CancelNotification(CancelNotification),
    MessageMcpNotification(MessageMcpNotification),
    ExtNotification(ExtNotification),
}

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

This enum is used internally for routing RPC notifications. You typically won’t need to use this directly.

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.

CancelNotification(CancelNotification)

Cancels ongoing operations for a session.

This is a notification sent by the client to cancel an ongoing prompt turn.

Upon receiving this notification, the Agent SHOULD:

• Stop all language model requests as soon as possible
• Abort all tool call invocations in progress
• Send any pending session/update notifications
• Respond to the original session/prompt request with StopReason::Cancelled

See protocol docs: Cancellation

MessageMcpNotification(MessageMcpNotification)

Available on crate feature unstable_mcp_over_acp only.

UNSTABLE

This capability is not part of the spec yet, and may be removed or changed at any point.

Sends an MCP-over-ACP notification.

ExtNotification(ExtNotification)

Handles extension notifications from the client.

Extension notifications provide a way to send one-way messages for custom functionality while maintaining protocol compatibility.

See protocol docs: Extensibility
