Struct ViewRefInstalled 

pub struct ViewRefInstalled;

The type corresponding to the ViewRefInstalled protocol. A method of enabling ViewRef holders to determine if a ViewRef has been “installed” in the view tree: the time it is first connected, transitively, to the root view. Typically, after installation, view focus may be transferred to that ViewRef.

Note: It’s important to distinguish between a ViewRef’s installed status and current connected-to-view-tree status. The former undergoes a state change once, from “no” to “yes”. The latter may change continuously, depending on view tree topology. As such, “installed” cannot imply “currently connected to view tree”; even a hypothetical “ViewRefConnected” protocol is fundamentally racy.

impl<___T> HasConnectionHandles<___T> for ViewRefInstalled

where ___T: Transport,

type Client = ViewRefInstalledClient<___T>

The client for the protocol. It must be a #[repr(transparent)] wrapper around Client<T>.

type Server = ViewRefInstalledServer<___T>

The server for the protocol. It must be a #[repr(transparent)] wrapper around Server<T>.

impl HasTransport for ViewRefInstalled

Available on Fuchsia only.

type Transport = Channel

The default transport type for this protocol.

impl PartialEq for ViewRefInstalled

fn eq(&self, other: &ViewRefInstalled) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
