Implementations

impl UsageWatcher2SynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<UsageWatcher2Event, 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 on_state_changed( &self, usage: &Usage2, state: &UsageState, ___deadline: MonotonicInstant, ) -> Result<(), Error>

Called on first connection and whenever the watched usage changes. The provided usage will always be the bound usage; it is provided so that an implementation of this protocol may be bound to more than one usage.

Clients must respond to acknowledge the event. Clients that do not acknowledge their events will eventually be disconnected.
