Pure-virtual interface to be implemented by a server.
This interface uses typed channels (i.e. |::fidl::ClientEnd
<
::fuchsia_ui_observation_geometry::ViewTreeWatcher>|
and |::fidl::ServerEnd
<
::fuchsia_ui_observation_geometry::ViewTreeWatcher>|).
Public Methods
void Watch (WatchCompleter::Sync & completer)A method of obtaining view tree snapshots for a particular view.
This call is formulated as a "hanging get" pattern: the client asks for
a set of recent snapshots, and receives them via the callback. This
pull-based approach ensures that clients consume events at their own
pace; events don't clog up the channel in an unbounded manner.
Error Handling. If Error is unset, the client may assume that the
the response contains updates with complete information over its epoch.
Flow control. The caller is allowed at most one in-flight |Watch| call
at a time; it is a logical error to have concurrent calls to |Watch|.
Non-compliance results in channel closure.
Client pacing. The server will dispatch snapshots to the caller on a
lossless, best-effort basis, but the caller must allocate enough time to
keep up with new snapshots.

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.
