Trait Implementations

impl AsRaw<libinput_event_gesture> for GesturePinchBeginEvent

fn as_raw(&self) -> *const libinput_event_gesture

Receive a raw pointer representing this type.

impl Context for GesturePinchBeginEvent

fn context(&self) -> &Libinput

Returns the underlying libinput context

impl Debug for GesturePinchBeginEvent

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

Formats the value using the given formatter.

impl Drop for GesturePinchBeginEvent

fn drop(&mut self)

Executes the destructor for this type.

impl EventTrait for GesturePinchBeginEvent

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 GesturePinchBeginEvent

unsafe fn from_raw(ffi: *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 GesturePinchBeginEvent

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 GesturePinchBeginEvent

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 GesturePinchBeginEvent

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