Implementations

impl ProviderSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<ProviderEvent, 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 initialize(&self, config: ProviderConfig) -> Result<(), Error>

Initialize tracing and prepare for writing trace records for events in the specified categories into buffer using fifo for signaling. Tracing hasn’t started yet, a Start() call is still required.

At most one trace can be active at a time. Subsequent Initialize() requests received prior to a Terminate() call must be ignored.

pub fn start(&self, options: &StartOptions) -> Result<(), Error>

Begin tracing.

If tracing has already started the provider must ignore the request.

There is no result. The provider must send a TRACE_PROVIDER_STARTED packet on fifo to indicate success/failure of starting.

pub fn stop(&self) -> Result<(), Error>

Stop tracing.

If tracing has already stopped the provider must ignore the request.

Once the provider has finished writing any final events to the trace buffer, it must send a TRACE_PROVIDER_STOPPED packet on fifo. Note that multiple Start,Stop requests can be received between Initialize,Terminate.

pub fn terminate(&self) -> Result<(), Error>

Terminate tracing.

Tracing is stopped first if not already stopped. After tracing has fully terminated the provider must close both buffer and fifo to indicate to the trace manager that tracing is finished.

pub fn get_known_categories( &self, ___deadline: MonotonicInstant, ) -> Result<Vec<KnownCategory>, Error>

Gets the trace categories that might be produced by this provider.
