Provides updates from a Coordinator to one of its clients.

Variants

OnDisplaysChanged

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.

Fields

added: Vec<Info>

removed: Vec<DisplayId>

control_handle: CoordinatorListenerControlHandle

OnVsync

Called on every display Vertical Synchronization (Vsync) signal.

Fields

display_id: DisplayId

timestamp: i64

applied_config_stamp: ConfigStamp

cookie: VsyncAckCookie

control_handle: CoordinatorListenerControlHandle

OnClientOwnershipChange

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.

Fields

has_ownership: bool

control_handle: CoordinatorListenerControlHandle

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: CoordinatorListenerControlHandle

method_type: MethodType
