Struct StatusWatcherSynchronousProxy

pub struct StatusWatcherSynchronousProxy { /* private fields */ }

Implementations

impl StatusWatcherSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<StatusWatcherEvent, 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_status( &self, ___deadline: MonotonicInstant, ) -> Result<PortStatus, Error>

WatchStatus blocks until the port’s status has changed.

The first call to WatchStatus returns immediately with the current port status, subsequent calls complete when the port status differs from the last one that was returned through this StatusWatcher.

If StatusWatcher was created with a buffer value larger than 1, WatchStatus may return a queued status change, depending on how many status changed happened since the last call to WatchStatus.

• response device_status the most recent port status.
