The provisioner interface used by the trace tool to initialize tracing

The provisioner is required to start a tracing session and bind the control to the client. It can also perform tasks like getting the list of registered providers and known categories, which can be performed without a existing trace session.

Variants

InitializeTracing

Requests to initialize tracing with the specified config.

A bad request will terminate the connection.

The trace controller emits trace data to output as a sequence of binary formatted trace records. Traces obtained from different providers are delimited by metadata records within the stream. The format of these records can be found here: https://fuchsia.dev/fuchsia-src/reference/tracing/trace-format

Fields

controller: ServerEnd<SessionMarker>

config: TraceConfig

output: Socket

control_handle: ProvisionerControlHandle

GetProviders

Return the set of registered providers.

Fields

responder: ProvisionerGetProvidersResponder

GetKnownCategories

Fields

responder: ProvisionerGetKnownCategoriesResponder

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: ProvisionerControlHandle

method_type: MethodType
