Struct SvcDirectoryWatcherSynchronousProxy

pub struct SvcDirectoryWatcherSynchronousProxy { /* private fields */ }

Implementations

impl SvcDirectoryWatcherSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<SvcDirectoryWatcherEvent, 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 watch_service_directory( &self, ___deadline: MonotonicInstant, ) -> Result<Vec<HostPort>, Error>

Returns a vector of HostPorts for the watched endpoint ID.

First call returns the current list of HostPorts or blocks until the list is available from the service. Subsequent calls will block until a new ServiceDirectory lookup is made and will return the list associated with the watched endpoint ID, which may or may not be the same as prior values.

Calling WatchServiceDirectory when a previous call is still pending will cause the channel to be closed with ZX_ERR_BAD_STATE.
