pub struct ProviderV2SynchronousProxy { /* private fields */ }

Implementations

impl ProviderV2SynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<ProviderV2Event, 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: ProviderConfigV2) -> Result<(), Error>

Initialize tracing and prepare for writing trace records for events in the specified categories into buffer. 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, ___deadline: MonotonicInstant, ) -> Result<(), Error>

Begin tracing.

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

pub fn stop(&self, ___deadline: MonotonicInstant) -> 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 an OnStopped() event. Note that multiple Start,Stop requests can be received between Initialize,Terminate.

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

Terminate tracing.

Tracing is stopped first if not already stopped.

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

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

pub fn notify_buffer_saved( &self, wrapped_count: u32, durable_data_end: u64, ) -> Result<(), Error>

A buffer has been saved (streaming mode only).

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

Requests the provider its buffer to be read out, regardless of it is full or not.

Normally streaming mode only sends data once it has enough data to require a buffer swap and data flush. This produces fewer, but larger and bursty data transfers.

Some clients may want more regular smaller data transfers. These clients may instead manually invoke Flush whenever they are ready for data.
