}

The protocol endpoints bound to a Flatland ViewCreationToken. These protocols operate on the View that ViewCreationToken created in the Flatland session.

Fields

view_ref_focused: Option<ServerEnd<ViewRefFocusedMarker>>

Learn when a View gains focus.

Server-bound ViewRef. The [view_ref_focused] client does not specify the ViewRef explicitly; instead, the server implementation uses the ViewRef used in View creation for reporting focus movement on/off this View.

view_focuser: Option<ServerEnd<FocuserMarker>>

Enable a View to request focus transfer to a child (target) View.

Server-bound ViewRef. The [view_focuser] client does not specify the “requestor” ViewRef explicitly, only the “target” ViewRef. Instead, the server implementation uses the ViewRef used in View creation as the “requestor” ViewRef.

touch_source: Option<ServerEnd<TouchSourceMarker>>

Receive touch events that are associated with a View.

mouse_source: Option<ServerEnd<MouseSourceMarker>>

Receive mouse events that are associated with a View.

Trait Implementations

impl Debug for ViewBoundProtocols

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Decode<ViewBoundProtocols> for ViewBoundProtocols

fn new_empty() -> ViewBoundProtocols

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_>, offset: usize, depth: Depth ) -> Result<(), Error>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for ViewBoundProtocols

fn default() -> ViewBoundProtocols

Returns the “default value” for a type.

impl Encode<ViewBoundProtocols> for &mut ViewBoundProtocols

unsafe fn encode( self, encoder: &mut Encoder<'_>, offset: usize, depth: Depth ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for ViewBoundProtocols

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl ResourceTypeMarker for ViewBoundProtocols

type Borrowed<'a> = &'a mut ViewBoundProtocols

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &mut Self::Owned. There are three cases:

fn take_or_borrow<'a>( value: &'a mut <ViewBoundProtocols as TypeMarker>::Owned ) -> <ViewBoundProtocols as ResourceTypeMarker>::Borrowed<'a>

Cheaply converts from &mut Self::Owned to Self::Borrowed. For HandleBased types this is “take” (it returns an owned handle and replaces value with Handle::invalid), and for all other types it is “borrow” (just converts from one reference to another).

impl TypeMarker for ViewBoundProtocols

type Owned = ViewBoundProtocols

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.
