Struct RegistryProxy

pub struct RegistryProxy { /* private fields */ }

Implementations

impl RegistryProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.tracing.provider/Registry.

pub fn take_event_stream(&self) -> RegistryEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn register_provider( &self, provider: ClientEnd<ProviderMarker>, pid: u64, name: &str, ) -> Result<(), Error>

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.

pub fn register_provider_synchronously( &self, provider: ClientEnd<ProviderMarker>, pid: u64, name: &str, ) -> QueryResponseFut<(i32, bool), DefaultFuchsiaResourceDialect>

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.
