        pid: u64,
        name: String,

    },
}

The service which trace providers use to register themselves with the tracing system. Note that one property of this interface is that once registration is made the provider can drop this connection.

Variants

RegisterProvider

Registers the trace provider. Note: Registration is asynchronous, it’s only at some point after this returns that the provider is actually registered. To unregister, simply close the Provider pipe. pid is the process id of the provider, name is the name of the provider. Both of these are used in logging and diagnostic messages.

Deprecation

Use “RegisterV2” instead to use the FIDL-based coordination protocol.

Fields

provider: ClientEnd<ProviderMarker>

pid: u64

name: String

control_handle: RegistryControlHandle

RegisterProviderSynchronously

Registers the trace provider synchronously. The call doesn’t return until the provider is registered. On return s is ZX_OK if registration was successful. started is true if tracing has already started, which is a hint to the provider to wait for the Start() message before continuing if it wishes to not drop trace records before Start() is received. To unregister, simply close the Provider pipe. pid is the process id of the provider, name is the name of the provider. Both of these are used in logging and diagnostic messages.

Deprecation

Use “RegisterV2Synchronously” instead to use the FIDL-based coordination protocol.

Fields

provider: ClientEnd<ProviderMarker>

pid: u64

name: String

responder: RegistryRegisterProviderSynchronouslyResponder

RegisterV2

Registers the trace provider using the V2 protocol.

Note: Registration is asynchronous, it’s only at some point after this returns that the provider is actually registered.

To unregister, close the provider connection.

Fields

provider: ClientEnd<ProviderV2Marker>

pid: u64

name: String

control_handle: RegistryControlHandle

RegisterV2Synchronously

Registers the trace provider synchronously using the V2 protocol.

The call doesn’t return until the provider is registered. Most callers should use RegisterV2 unless they need to synchronize with they tracing system to ensure that specific events are captured.

To unregister, close the provider connection.

Fields

provider: ClientEnd<ProviderV2Marker>

pid: u64

name: String

responder: RegistryRegisterV2SynchronouslyResponder

#[non_exhaustive]

_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: RegistryControlHandle

method_type: MethodType
