Struct PortWatcherProxy

pub struct PortWatcherProxy { /* private fields */ }

Implementations

impl PortWatcherProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.network/PortWatcher.

pub fn take_event_stream(&self) -> PortWatcherEventStream

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

Panics

Panics if the event stream was already taken.

pub fn watch( &self, ) -> QueryResponseFut<DevicePortEvent, DefaultFuchsiaResourceDialect>

Get the next port event.

The first N calls return [DevicePortEvent.existing] where N is the number of ports present on the device at the time of the watcher’s creation. The next call returns [DevicePortEvent.idle] to indicate the end of existing ports. Subsequent calls block until a port is added ([DevicePortEvent.added]) or removed ([DevicePortEvent.removed]).

The server closes the PortWatcher channel with ZX_ERR_CANCELED if the number of unread events reaches a server-selected limit that is at least two times MAX_PORTS. Clients are encouraged to maintain a hanging call to Watch at all times to avoid triggering this condition.

• response event next port event.
