Functions

• bool ImportBufferCollection (allocation::GlobalBufferCollectionId buffer_collection_id, const fidl::WireSharedClient<fuchsia_hardware_display::Coordinator> & display_coordinator, fidl::ClientEnd<fuchsia_sysmem2::BufferCollectionToken> token, const fuchsia_hardware_display_types::wire::ImageBufferUsage & image_buffer_usage)

  Imports a sysmem buffer collection token to a display controller, and sets the constraints.

  A successful import will return true, otherwise it will return false.

• fpromise::promise<CoordinatorClientChannels, zx_status_t> GetCoordinator (fidl::ClientEnd<fuchsia_hardware_display::Provider> provider, async_dispatcher_t * dispatcher)

  Connects to the [`fuchsia.hardware.display/Coordinator`] protocol using the

  `provider` client. The FIDL connection is asynchronously performed on

  `dispatcher`.

  Returns a promise which will be resolved when the display coordinator is

  obtained on success, if the display provider service is available and can

  be connected; otherwise returns a fpromise::error.

  TODO(https://fxbug.dev/500852294): Add ClientPriority argument.

• template <typename Lambda>

  bool PollUntil (Lambda predicate, zx::duration poll_interval, int max_intervals)

  Polls a predicate periodically, until it becomes true or we time out.

  Returns true for success, meaning the predicate was true last time it was

  polled. Returns false for failure, meaning the predicate did not become true

  within the timeout.

  `poll_interval` is time interval between polls. Popular values are zx::nsec(1)

  and zx::usec(1).

  `max_intervals` is the number of intervals to wait before timing out. If

  `predicate` is not true after this many intervals, the function returns

  false.

• EventId ImportEventForTest (const fidl::WireSharedClient<fuchsia_hardware_display::Coordinator> & display_coordinator, const zx::event & event)

  Imports a zx::event to the provided display controller. The return value is an ID to

  reference that event on other display controller functions that take an event as an

  argument. On failure, the return value will be fuchsia_hardware_display_types::kInvalidDispId.

  Deprecated. Prefer to use `CoordinatorProxy::ImportEvent()`.

  dispatcher.

  Imports an image to be used for capture (i.e. screenshotting) of the display

  controller, associated with `capture_image_id`.

  `capture_image_id` must not be used for any images, including images

  imported for display.

  On failure, this function returns the error value.

• template <size_t inline_target_size = fit::default_inline_target_size>

  zx::result<> PostTask (async_dispatcher_t & dispatcher, fit::inline_callback<void (), inline_target_size> callback)

  Arranges for `callback` to run on `dispatcher` as a posted task.

  This overload only performs checked dynamic memory allocation. All memory

  allocation errors will be reported via the PostTask() returned result. So,

  once PostTask() succeeds, no further dynamic memory allocation will be

  performed.

  `inline_target_size` is the capacity for storing `callback`'s captures. A

  compilation error will occur when attempting to use a callback whose captured

  state size exceeds this capacity.

  `callback` must be callable until it is called, or until `dispatcher` is shut

  down, whichever comes first. This implies that `callback` must be non-null.

  `callback` will be run when `dispatcher` invokes the posted task. So,

  `callback` will always be executed from one of the dispatcher's threads. The

  state captured in `callback` will be destroyed right after `callback` is run,

  on the same thread.

  `callback` must be moveable (implying that the captured context must be

  moveable) while it is callable. The move operators may be called on the

  thread used to call `PostTask()`, or on any of the dispatcher's threads.

  `callback` will not be run if `dispatcher` is shut down before it processes

  the posted task. In that case, the state captured in `callback` will be

  destroyed while the dispatcher is shutting down. The captured state will

  either be destroyed synchronously in PostTask() or on a dispatcher thread,

  depending on the relative timing of PostTask() and the dispatcher shutdown.

  Returns ZX_ERR_NO_MEMORY if dynamic memory allocation fails. Also exhibits

  all failure modes of the underlying C API `async_post_task()`.

  zx::result<> PostTask (std::unique_ptr<PostTaskState<inline_target_size>> post_task_state, async_dispatcher_t & dispatcher, fit::inline_callback<void (), inline_target_size> task_callback)

  Arranges for `callback` to run on `dispatcher` as a posted task.

  This overload does not perform any dynamic memory allocation. The consumed

  `post_task_state` is used instead. The caller must not attempt to access

  `post_task_state` in any way (such as a stashed raw pointer) after passing it

  into this call.

  `inline_target_size` is the capacity for storing `callback`'s captures. The

  compiler can infer this argument from the type of `post_task_state`. A

  compilation error will occur when attempting to use a callback whose captured

  state size exceeds this capacity.

  `callback` must be callable until it is called, or until `dispatcher` is shut

  down, whichever comes first. This implies that `callback` must be non-null.

  `callback` will be run when `dispatcher` invokes the posted task. So,

  `callback` will always be executed from one of the dispatcher's threads. The

  state captured in `callback` will be destroyed right after `callback` is run,

  on the same thread.

  thread used to call `PostTask()`, or on any of the dispatcher's threads.

  `callback` will not be run if `dispatcher` is shut down before it processes

  the posted task. In that case, the state captured in `callback` will be

  destroyed while the dispatcher is shutting down. The captured state will

  either be destroyed synchronously in PostTask() or on a dispatcher thread,

  depending on the relative timing of PostTask() and the dispatcher shutdown.

  Returns any error produced by the underlying C API `async_post_task()`.
