Struct zng_view_api::touch::TouchUpdate

pub struct TouchUpdate {
    pub touch: TouchId,
    pub phase: TouchPhase,
    pub position: DipPoint,
    pub force: Option<TouchForce>,
}

Identify a new touch contact or a contact update.

Fields

touch: TouchId

Identify a continuous touch contact or finger.

Multiple points of contact can happen in the same device at the same time, this ID identifies each uninterrupted contact. IDs are unique only among other concurrent touches on the same device, after a touch is ended an ID may be reused.

phase: TouchPhase

Touch phase for the id.

position: DipPoint

Touch center, relative to the window top-left in device independent pixels.

force: Option<TouchForce>

Touch pressure force and angle.

Trait Implementations

impl Clone for TouchUpdate

fn clone(&self) -> TouchUpdate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TouchUpdate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TouchUpdate

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TouchUpdate

fn eq(&self, other: &TouchUpdate) -> 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 Serialize for TouchUpdate

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
