Struct ValueChange 

pub struct ValueChange<T> {
    pub source: Entity,
    pub value: T,
}

Notification sent by a widget that edits a scalar value.

Fields

source: Entity

The id of the widget that produced this value.

value: T

The new value.

Trait Implementations

impl<T: Clone> Clone for ValueChange<T>

fn clone(&self) -> ValueChange<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for ValueChange<T>

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

Formats the value using the given formatter.

impl<T> EntityEvent for ValueChange<T>

where Self: Send + Sync + 'static,

fn event_target(&self) -> Entity

The Entity “target” of this EntityEvent. When triggered, this will run observers that watch for this specific entity.

fn event_target_mut(&mut self) -> &mut Entity

Returns a mutable reference to the Entity “target” of this EntityEvent. When triggered, this will run observers that watch for this specific entity.

impl<T> Event for ValueChange<T>

where Self: Send + Sync + 'static,

type Trigger<'a> = EntityTrigger

Defines which observers will run, what data will be passed to them, and the order they will be run in. See Trigger for more info.

impl<T: PartialEq> PartialEq for ValueChange<T>

fn eq(&self, other: &ValueChange<T>) -> 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.
