Struct ContactInputReport

    pub contact_id: Option<u32>,
    pub position_x: Option<i64>,
    pub position_y: Option<i64>,
    pub pressure: Option<i64>,

}

ContactInputReport describes one touch on a touch device.

Fields

contact_id: Option<u32>

Identifier for this contact.

position_x: Option<i64>

A contact’s position on the x axis.

position_y: Option<i64>

A contact’s position on the y axis.

pressure: Option<i64>

Pressure of the contact.

contact_width: Option<i64>

Width of the bounding box around the touch contact. Combined with contact_height, this describes the area of the touch contact. contact_width and contact_height should both have units of distance, and they should be in the same units as position_x and position_y.

contact_height: Option<i64>

Height of the bounding box around the touch contact. Combined with contact_width, this describes the area of the touch contact. contact_width and contact_height should both have units of distance, and they should be in the same units as position_x and position_y.

confidence: Option<bool>

Also known as touch valid. Indicates the device’s confidence that the touch contact was an intended, valid contact. The device should report 0 if the contact is not a valid touch. The device should report 1 if the contact is intended and valid (e.g. a pointing touch)

Trait Implementations

impl Clone for ContactInputReport

fn clone(&self) -> ContactInputReport

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContactInputReport

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

Formats the value using the given formatter.

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

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 Default for ContactInputReport

fn default() -> ContactInputReport

Returns the “default value” for a type.

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

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 ContactInputReport

fn eq(&self, other: &ContactInputReport) -> 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 ContactInputReport

type Owned = ContactInputReport

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 ContactInputReport

type Borrowed<'a> = &'a ContactInputReport

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.
