Enum GesturePinchEvent

#[non_exhaustive]
pub enum GesturePinchEvent {
    Begin(GesturePinchBeginEvent),

}

Events for pinch gestures

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Begin(GesturePinchBeginEvent)

Pinch gesture began

Update(GesturePinchUpdateEvent)

In-progress pinch gesture updated

End(GesturePinchEndEvent)

Pinch gesture ended

Trait Implementations

impl AsRaw<libinput_event_gesture> for GesturePinchEvent

fn as_raw(&self) -> *const libinput_event_gesture

Receive a raw pointer representing this type.

impl Context for GesturePinchEvent

fn context(&self) -> &Libinput

Returns the underlying libinput context

impl Debug for GesturePinchEvent

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

Formats the value using the given formatter.

impl EventTrait for GesturePinchEvent

fn into_event(self) -> Event

where Self: Sized,

Convert into a general Event again

fn device(&self) -> Device

Return the device associated with this event.

impl FromRaw<libinput_event_gesture> for GesturePinchEvent

unsafe fn from_raw( event: *mut libinput_event_gesture, context: &Libinput, ) -> Self

Create a new instance of this type from a raw pointer and it’s context. If the type of the struct is a valid libinput type, but is unknown to this library, it panics instead.

impl GesturePinchEventTrait for GesturePinchEvent

fn scale(&self) -> f64

Return the absolute scale of a pinch gesture, the scale is the division of the current distance between the fingers and the distance at the start of the gesture.

fn into_gesture_pinch_event(self) -> GesturePinchEvent

where Self: Sized,

Convert into a general GesturePinchEvent

impl Hash for GesturePinchEvent

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for GesturePinchEvent

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