Struct display_mocks::MockCoordinator

pub struct MockCoordinator { /* private fields */ }

Expand description

MockCoordinator implements the server-end of the fuchsia.hardware.display.Coordinator protocol. It minimally reproduces the display coordinator driver state machine to respond to FIDL messages in a predictable and configurable manner.

Implementations§

impl MockCoordinator

pub fn new(server_end: ServerEnd<CoordinatorMarker>) -> Result<MockCoordinator>

Bind a new MockCoordinator to the server end of a FIDL channel.

pub fn assign_displays(&mut self, displays: Vec<Info>) -> Result<()>

Replace the list of available display devices with the given collection and send a fuchsia.hardware.display.Coordinator.OnDisplaysChanged event reflecting the changes.

All the new displays will be reported as added while previously present displays will be reported as removed, regardless of their content.

Returns an error if displays contains entries with repeated display IDs.

pub fn emit_vsync_event( &self, display_id_value: u64, stamp: ConfigStamp ) -> Result<()>

Sends a single OnVsync event to the client. The vsync event will appear to be sent from the given display_id even if a corresponding fake display has not been assigned by a call to assign_displays.
