Struct SessionProxy

pub struct SessionProxy { /* private fields */ }

Implementations

impl SessionProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.tracing.controller/Session.

pub fn take_event_stream(&self) -> SessionEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn start_tracing( &self, payload: &StartOptions, ) -> QueryResponseFut<SessionStartTracingResult, DefaultFuchsiaResourceDialect>

Requests to start tracing with the specified options.

If tracing has already started then the request is ignored, except to send back an error code.

The trace Session acknowledges the request when all registered providers have been started or after TraceConfig.start_timeout_milliseconds milliseconds. One useful reason for the has-started acknowledgement is that the trace program can start a program to trace knowing that all the providers are started.

pub fn stop_tracing( &self, payload: &StopOptions, ) -> QueryResponseFut<SessionStopTracingResult, DefaultFuchsiaResourceDialect>

Requests to stop tracing.

If tracing has already stopped then this does nothing. Returning a result lets callers know when it’s ok to, for example, start tracing again.

pub fn watch_alert( &self, ) -> QueryResponseFut<String, DefaultFuchsiaResourceDialect>

Returns the next alert when it arrives.

Alerts received by the Session are queued until a WatchAlert request is received. Alerts are sent to the caller in the order they were received.

WatchAlert requests are also queued until an alert is received and the requests are serviced in the order they were received.

Trait Implementations

impl Clone for SessionProxy

fn clone(&self) -> SessionProxy

fn is_closed(&self) -> bool

Returns true if the proxy has received the PEER_CLOSED signal.

fn on_closed(&self) -> OnSignals<'_, Unowned<'_, Handle>>

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
