Pure-virtual interface to be implemented by a server.
This interface uses typed channels (i.e. |::fidl::ClientEnd
<
::fuchsia_ui_composition::ParentViewportWatcher>|
and |::fidl::ServerEnd
<
::fuchsia_ui_composition::ParentViewportWatcher>|).
Public Methods
void GetLayout (GetLayoutCompleter::Sync & completer)A hanging get for receiving layout information. Clients may receive layout information
before the ParentViewportWatcher operation has been presented. This allows children to
layout their content before their first call to [`Present`]. In transition cases where two
ParentViewportWatcher channels exist at the same time, both protocol instances will be
receiving different layout information.
This hanging get will only fire when the LayoutInfo is different than the previously
returned LayoutInfo. Note that, since LayoutInfo is a table, only some fields may have
changed.
It is invalid to call `GetLayout` while a previous call is still pending. Doing so will
cause both this channel and the Flatland channel that handed out ParentViewportWatcher to be
closed.
void GetStatus (GetStatusCompleter::Sync & completer)A hanging get for receiving the status of the parent Viewport. This provides global
connectivity information to the child.
This hanging get will only fire when the ParentViewportStatus is different than the
previously returned ParentViewportStatus.
It is invalid to call `GetStatus` while a previous call is still pending. Doing so will
cause both this channel and the Flatland channel that handed out ParentViewportWatcher to be
closed.

Handler bind_handler (async_dispatcher_t * dispatcher)|bind_handler| returns a handler that binds incoming connections to this
server implementation.
The returned handler borrows the server instance.
The server must outlive the provided |dispatcher|. Only after
the dispatcher is shutdown will it be safe to destroy the servers.
The server should not be moved.
