Struct TouchEventWithLocalHit

pub struct TouchEventWithLocalHit {
    pub touch_event: TouchEvent,
    pub local_viewref_koid: u64,
    pub local_point: [f32; 2],
}

An augmentation of [fuchsia.ui.pointer.TouchEvent] to provide local-hit data for a touch event.

For a given touch event e, consider the ordered list of intersections with graphical content: its “hits” from top to bottom. The “local hit” of e is the location of e in the coordinate system of the view in which e has the top-most intersection.

Fields

touch_event: TouchEvent

Identical usage to [fuchsia.ui.pointer.TouchEvent].

local_viewref_koid: u64

Augmented data for touch_event that describes the top-most client KOID that it hits.

local_point: [f32; 2]

Augmented data for touch_event that describes its local coordinates in the coordinate space for local_viewref_koid.

Trait Implementations

impl Clone for TouchEventWithLocalHit

fn clone(&self) -> TouchEventWithLocalHit

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TouchEventWithLocalHit

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<TouchEventWithLocalHit, D> for TouchEventWithLocalHit

fn new_empty() -> Self

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<'_, D>, offset: usize, _depth: Depth, ) -> Result<()>

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

impl<D: ResourceDialect> Encode<TouchEventWithLocalHit, D> for &TouchEventWithLocalHit

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

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

impl<D: ResourceDialect, T0: Encode<TouchEvent, D>, T1: Encode<u64, D>, T2: Encode<Array<f32, 2>, D>> Encode<TouchEventWithLocalHit, D> for (T0, T1, T2)

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

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

impl PartialEq for TouchEventWithLocalHit

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

impl TypeMarker for TouchEventWithLocalHit

type Owned = TouchEventWithLocalHit

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.

impl ValueTypeMarker for TouchEventWithLocalHit

type Borrowed<'a> = &'a TouchEventWithLocalHit

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

fn borrow(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
