Struct SamplerProxy

pub struct SamplerProxy { /* private fields */ }

Implementations

impl SamplerProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.memory.sampler/Sampler.

pub fn take_event_stream(&self) -> SamplerEventStream

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

Panics

Panics if the event stream was already taken.

pub fn record_allocation( &self, address: u64, stack_trace: &StackTrace, size: u64, ) -> Result<(), Error>

Record an allocation.

pub fn record_deallocation( &self, address: u64, stack_trace: &StackTrace, ) -> Result<(), Error>

Record a deallocation.

pub fn set_process_info( &self, payload: &SamplerSetProcessInfoRequest, ) -> Result<(), Error>

Communicate relevant process information to facilitate symbolization.

If called several times, the last process_name prevails, but the module_map is added to the existing map for the process. If a client needs to send a module_map that does not fit in a single message, they can split it and send it across several messages.

fn on_closed(&self) -> OnSignals<'_, Unowned<'_, Handle>>

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
