class TrackEventInternal

Defined at line 216 of file ../../third_party/perfetto/include/perfetto/tracing/internal/track_event_internal.h

The backend portion of the track event trace point implemention. Outlined to

a separate .cc file so it can be shared by different track event category

namespaces.

void WriteTrackDescriptorIfNeeded (const TrackType & track, TraceWriterBase * trace_writer, TrackEventIncrementalState * incr_state, const TrackEventTlsState & tls_state, const TraceTimestamp & timestamp)

If the given track hasn't been seen by the trace writer yet, write a

descriptor for it into the trace. Doesn't take a lock unless the track

descriptor is new.

template <typename TrackType>

uint64_t WriteTrackDescriptor (const TrackType & track, TraceWriterBase * trace_writer, TrackEventIncrementalState * incr_state, const TrackEventTlsState & tls_state, const TraceTimestamp & timestamp)

Unconditionally write a track descriptor into the trace.

Returns the parent track uuid.
