Library providing methods for connecting Perfetto clients to a system tracing service.
PROTOCOLS
BufferReceiver
Defined in fuchsia.tracing.perfetto/producer.fidl
An interface for exchanging trace data buffers between Providers and the system tracing service.
ProvideBuffer
Sends a file to be used as a trace buffer. The file must support writable mmap() access.

ConsumerConnector
Defined in fuchsia.tracing.perfetto/consumer.fidl
Interface for creating connections between Perfetto "Consumers" and a shared Perfetto service. To learn more about Perfetto, see: https://www.perfetto.dev/docs/ and https://perfetto.dev/docs/concepts/service-model .
ConnectConsumer
Connects a Perfetto Consumer to the Perfetto backend. Both sides
will communicate over producer_socket using Perfetto's internal wire
format.
The lifetime of consumer_socket may outlive the connection lifetime
of ConsumerConnector.
Multiple producers may be connected simultaneously.

ProducerConnector
Defined in fuchsia.tracing.perfetto/producer.fidl
Interface for creating connections between Perfetto "Producers" and a shared Perfetto service. To learn more about Perfetto, see: https://www.perfetto.dev/docs/ and https://perfetto.dev/docs/concepts/service-model .
ConnectProducer
Connects a Perfetto Producer to the Perfetto backend. Both sides
will communicate over producer_socket using Perfetto's internal
wire format "ProducerPort" (see
//third_party/perfetto/protos/perfetto/ipc/producer_port.proto).
trace_buffer either provides a buffer for communicating trace data
from the client, or an interface for receiving a buffer from the
server, depending on the client's needs.
The lifetime of producer_socket may outlive the connection lifetime
of ProducerConnector.
Multiple Producers may be connected simultaneously.
