Implementations

impl SessionSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<SessionEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn start_tracing( &self, options: &StartOptions, ___deadline: MonotonicInstant, ) -> Result<SessionStartTracingResult, Error>

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 controller 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, options: &StopOptions, ___deadline: MonotonicInstant, ) -> Result<SessionStopTracingResult, Error>

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, ___deadline: MonotonicInstant, ) -> Result<String, Error>

Returns the next alert when it arrives.
