Enum MotionPredicate 

pub enum MotionPredicate {
    Hovered(WidgetId),
    Pressed(WidgetId),
    Focused(WidgetId),
    Disabled(WidgetId),
}

Runtime interaction predicate that can branch inside a MotionExpr.

Predicates are evaluated by the shell from deterministic runtime state, not by calling user code every frame.

Variants

Hovered(WidgetId)

True when the widget is currently hovered.

Pressed(WidgetId)

True when the widget is currently pressed.

Focused(WidgetId)

True when the widget is currently focused.

Disabled(WidgetId)

True when the widget is disabled.

Trait Implementations

impl Clone for MotionPredicate

fn clone(&self) -> MotionPredicate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MotionPredicate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MotionPredicate

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for MotionPredicate

impl Hash for MotionPredicate

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 MotionPredicate

fn eq(&self, other: &MotionPredicate) -> 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 MotionPredicate

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
