pub struct CoordinatorListenerSynchronousProxy { /* private fields */ }

Implementations

impl CoordinatorListenerSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<CoordinatorListenerEvent, 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_displays_changed( &self, added: &[Info], removed: &[DisplayId], ) -> Result<(), Error>

Called when displays are added or removed. Called on client creation if there are any displays already connected.

A display change always invalidates the current configuration. When a CoordinatorListener receives this method call, the corresponding Coordinator client must either apply a new configuration or revalidate and reapply their current configuration.

added and removed must not be both empty.

pub fn on_vsync( &self, display_id: &DisplayId, timestamp: i64, applied_config_stamp: &ConfigStamp, cookie: &VsyncAckCookie, ) -> Result<(), Error>

Called on every display Vertical Synchronization (Vsync) signal.

pub fn on_client_ownership_change( &self, has_ownership: bool, ) -> Result<(), Error>

Called when the corresponding Coordinator client gains or loses ownership of the displays.

A Coordinator client’s active config is displayed iff it holds the ownership of the displays.

A new Coordinator client should assume they do not have ownership of the displays until this method informs them otherwise.
