    Gesture {

Fields

id: u64

Contact identifier.

pos: Point

New position.

End

A finger lifted off.

Fields

id: u64

Contact identifier.

pos: Point

Position at release.

Cancel

The contact was cancelled by the system (e.g. palm rejection).

Implementations

impl TouchEvent

pub fn touch_id(&self) -> Option<u64>

The stable touch id, or None for centroid-only gesture events.

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 Copy for TouchEvent

impl Debug for TouchEvent

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

Formats the value using the given formatter.

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.
