Implementations

impl WatcherSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

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

Hanging get for an interface addition/deletion change.

Clients should only have one call of this method at a time; a second call to this method while a call is already pending will cause the server end of the protocol to be closed.

If there are N interfaces present at the time the server end of the protocol is initialized, then the first N invocations of this method will return [Event.existing] followed by a single [Event.idle] indicating that all existing interfaces have been sent. Subsequent calls will immediately return if there is a change to be reported, or block until a change occurs.

The server may choose to coalesce property change events, e.g. when multiple independent property changes occur. As a result, clients cannot assume that the order in which they observe the interface changes is the order in which the changes occurred.

• response event the interface change event.
