::fidl::WireResult< ::fuchsia_ui_views::ViewRefInstalled::Watch> Watch (::fuchsia_ui_views::wire::ViewRef && view_ref)Sets up a callback to fire when the requested |view_ref| is installed.
- If |view_ref| has not already been installed, the |Watch| response
will fire when it is.
- If |view_ref| has already been installed, the |Watch| response will
fire immediately.
- If |view_ref| is invalid, or becomes invalid (perhaps because the view
was destroyed), the |Watch| call returns with an error. The error is
not guaranteed to be immediate, but a ViewRef holder can itself
determine ViewRef validity by listening for ZX_EVENTPAIR_PEER_CLOSED.
Flow control: The caller is allowed multiple |Watch| calls on multiple
ViewRefs. There is at most one response per call back to the client.
Note: Prior to installation, this |Watch| call is kept alive as long as
the ViewRef is valid.
Allocates 56 bytes of message buffer on the stack. No heap allocation necessary.
