Struct ViewRefFocused 

pub struct ViewRefFocused;

The type corresponding to the ViewRefFocused protocol. A method of enabling a ViewRef creator to determine if its ViewRef has gained or lost focus in the view tree.

The protocol client has implicit access to the ViewRef it created; the protocol itself does not accept a ViewRef parameter. Clients, both trusted or otherwise, need access to view-focus state, so the protocol is deliberately minimal. Possession of a ViewRef (and this protocol) does not grant the power to learn about a ViewRef’s focus state.

impl<___T> HasConnectionHandles<___T> for ViewRefFocused

where ___T: Transport,

type Client = ViewRefFocusedClient<___T>

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

type Server = ViewRefFocusedServer<___T>

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

impl HasTransport for ViewRefFocused

Available on Fuchsia only.

type Transport = Channel

The default transport type for this protocol.

impl PartialEq for ViewRefFocused

fn eq(&self, other: &ViewRefFocused) -> 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.
