Enum PortWatcherRequest 

pub enum PortWatcherRequest {
    Watch {
        responder: PortWatcherWatchResponder,
    },
}

Provides iteration over and updates for ports attached to a device.

Variants

Watch

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.
