pub trait StatusWatcherLocalServerHandler<___T: Transport = Channel> {
    // Required method
    fn watch_status(
        &mut self,
        responder: Responder<WatchStatus, ___T>,
    ) -> impl Future<Output = ()>;
}

A server handler for the StatusWatcher protocol.

Required Methods

fn watch_status( &mut self, responder: Responder<WatchStatus, ___T>, ) -> impl Future<Output = ()>

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
