Struct TouchEvent 

pub struct TouchEvent {
    pub phase: TouchPhase,
    pub touches: Vec<TouchPoint>,
    pub timestamp_ms: u64,
    pub target_element: Option<ElementId>,
}

A touch event with one or more touch points.

Fields

phase: TouchPhase

Phase of this touch event.

touches: Vec<TouchPoint>

All current touch points.

timestamp_ms: u64

Timestamp in milliseconds since canvas start.

target_element: Option<ElementId>

Element ID that was touched (if any).

Implementations

impl TouchEvent

pub fn new( phase: TouchPhase, touches: Vec<TouchPoint>, timestamp_ms: u64, ) -> Self

Create a new touch event.

pub fn primary_touch(&self) -> Option<&TouchPoint>

Get the primary (first) touch point.

pub fn is_multi_touch(&self) -> bool

Check if this is a multi-touch event.

Trait Implementations

impl Clone for TouchEvent

fn clone(&self) -> TouchEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TouchEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TouchEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TouchEvent

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
