class Controller
Defined at line 59 of file ../../src/graphics/display/drivers/coordinator/controller.h
Multiplexes between display controller clients and display engine drivers.
Instances are not thread-safe, and must only be used on the driver
dispatcher.

zx::result<std::unique_ptr<Controller>> Create (std::unique_ptr<EngineDriverClient> engine_driver_client, fdf::UnownedSynchronizedDispatcher driver_dispatcher)Factory method for production use.
Creates and initializes a Controller instance.
Asynchronous work that manages the state of the display clients and
coordinates the display state between clients and engine drivers runs on
`driver_dispatcher`.
`engine_driver_client` must not be null.
`driver_dispatcher` must be running until `PrepareStop()` is called.
`driver_dispatcher` must be shut down when `Stop()` is called.

void Controller (std::unique_ptr<EngineDriverClient> engine_driver_client, fdf::UnownedSynchronizedDispatcher driver_dispatcher)Creates a new coordinator Controller instance. It creates a new Inspector
which will be solely owned by the Controller instance.
`engine_driver_client` must not be null.

zx::result<std::span<const display::ModeAndId>> GetDisplayPreferredModes (display::DisplayId display_id)The display modes are guaranteed to be valid as long as the display with
`display_id` is valid.
For a valid display, it's guaranteed that `GetDisplayPreferredModes()` is
non-empty.

template <typename Callback>bool FindDisplayInfo (display::DisplayId display_id, Callback callback)Calls `callback` with a const DisplayInfo
&
matching the given `display_id`.
Returns true iff a DisplayInfo with `display_id` was found and `callback`
was called.
The controller mutex is guaranteed to be held while `callback` is called.

zx_status_t CreateClient (ClientPriority client_priority, fidl::ServerEnd<fuchsia_hardware_display::Coordinator> coordinator_server_end, fidl::ClientEnd<fuchsia_hardware_display::CoordinatorListener> coordinator_listener_client_end)Typically called by OpenController/OpenVirtconController. However, this is made public
for use by testing services which provide a fake display controller.
