Enum TouchpadGesturePhase

#[non_exhaustive]
pub enum TouchpadGesturePhase {
    Begin,
    Update,
    End,
    Cancel,
}

The phase of a touchpad gesture event. All gestures are guaranteed to begin with an event of type TouchpadGesturePhase::Begin, followed by a number of TouchpadGesturePhase::Update (possibly 0).

A finished gesture may have 2 possible outcomes, an event with phase TouchpadGesturePhase::End will be emitted when the gesture is considered successful, this should be used as the hint to perform any permanent changes.

Cancelled gestures may be so for a variety of reasons, due to hardware, or due to the gesture recognition layers hinting the gesture did not finish resolutely (eg. a 3rd finger being added during a pinch gesture). In these cases, the last event with report the phase TouchpadGesturePhase::Cancel, this should be used as a hint to undo any visible/permanent changes that were done throughout the progress of the gesture.

See also TouchpadPinchEvent and TouchpadPinchEvent.

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

The gesture has begun.

Update

The gesture has been updated.

End

The gesture was finished, changes should be permanently applied.

Cancel

The gesture was cancelled, all changes should be undone.

impl<'a> FromValue<'a> for TouchpadGesturePhase

unsafe fn from_value(value: &Value) -> Self

Safety

impl<'a> FromValueOptional<'a> for TouchpadGesturePhase

unsafe fn from_value_optional(value: &Value) -> Option<Self>

Safety

impl Hash for TouchpadGesturePhase

impl Ord for TouchpadGesturePhase

fn cmp(&self, other: &TouchpadGesturePhase) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq for TouchpadGesturePhase

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