Implementations

impl PublisherSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<PublisherEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn publish( &self, data_sink: &str, data: Vmo, vmo_token: EventPair, ) -> Result<(), Error>

The program runtime sends a string naming a data_sink and transfers the handle to a VMO containing the data it wants published there. The data_sink string identifies a type of data, and the VMO’s object name can specifically identify the data set in this VMO. The ZX_PROP_VMO_CONTENT_SIZE property should be set on the VMO to indicate the precise size of the data in case that is not whole pages; however, leaving it unset (i.e. 0) is acceptable when the whole-page size of the VMO is the intended size of dump. Code instrumentation runtimes use this to deliver large binary trace results. In such cases, the client can resize the VMO and should use the vmo_token handle to signal when the VMO is ready for processing by the recipient. The receiver will not process the VMO until the peer of vmo_token handle is closed. Therefore, the client should retain the peer handle until it has completed all writes to the VMO.
