Struct NoopHandler 

pub struct NoopHandler;

A SessionHandler that leaves permission requests and external tool calls pending.

This is the default used when no handler is set on SessionConfig::handler. It lets consumers observe permission.requested and external_tool.requested events and later resolve them with the corresponding pending-request RPC methods.

impl SessionHandler for NoopHandler

fn on_event<'life0, 'async_trait>( &'life0 self, event: HandlerEvent, ) -> Pin<Box<dyn Future<Output = HandlerResponse> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Handle an event from the session.

fn on_session_event<'life0, 'async_trait>( &'life0 self, _session_id: SessionId, _event: SessionEvent, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Informational timeline event (assistant messages, tool execution markers, session idle, etc.). Fire-and-forget — the return value is ignored.

fn on_permission_request<'life0, 'async_trait>( &'life0 self, _session_id: SessionId, _request_id: RequestId, _data: PermissionRequestData, ) -> Pin<Box<dyn Future<Output = PermissionResult> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

The CLI is asking whether the agent may perform a privileged action.

fn on_user_input<'life0, 'async_trait>( &'life0 self, _session_id: SessionId, _question: String, _choices: Option<Vec<String>>, _allow_freeform: Option<bool>, ) -> Pin<Box<dyn Future<Output = Option<UserInputResponse>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

The CLI is asking the user a question (optionally with a list of choices).

fn on_external_tool<'life0, 'async_trait>( &'life0 self, invocation: ToolInvocation, ) -> Pin<Box<dyn Future<Output = ToolResult> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

The CLI wants to invoke a client-defined (“external”) tool.

fn on_elicitation<'life0, 'async_trait>( &'life0 self, _session_id: SessionId, _request_id: RequestId, _request: ElicitationRequest, ) -> Pin<Box<dyn Future<Output = ElicitationResult> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

The CLI is requesting an elicitation (structured form / URL prompt).

fn on_exit_plan_mode<'life0, 'async_trait>( &'life0 self, _session_id: SessionId, _data: ExitPlanModeData, ) -> Pin<Box<dyn Future<Output = ExitPlanModeResult> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

The CLI is asking the user whether to exit plan mode.

fn on_auto_mode_switch<'life0, 'async_trait>( &'life0 self, _session_id: SessionId, _error_code: Option<String>, _retry_after_seconds: Option<f64>, ) -> Pin<Box<dyn Future<Output = AutoModeSwitchResponse> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

The CLI is asking whether to switch to auto model after an eligible rate limit.
