pub struct MapBinding<TBinding: ?Sized, TMapValue, TMapFn> { /* private fields */ }

A map binding is a type of computed binding created by the BoundValueExt::map() function

Trait Implementations

impl<TBinding, TMapValue, TMapFn> Bound for MapBinding<TBinding, TMapValue, TMapFn>

where TBinding: 'static + Bound, TMapFn: 'static + Send + Sync + Fn(TBinding::Value) -> TMapValue, TMapValue: 'static + Send + Clone,

type Value = TMapValue

fn get(&self) -> Self::Value

Retrieves the value stored by this binding

fn watch(&self, what: Arc<dyn Notifiable>) -> Arc<dyn Watcher<Self::Value>>

Creates a watcher: this provides a way to retrieve the value stored in this binding, and will call the notification function if the value has changed since it was last read.

impl<TBinding, TMapValue, TMapFn> Changeable for MapBinding<TBinding, TMapValue, TMapFn>

where TBinding: 'static + Bound, TMapFn: 'static + Send + Sync + Fn(TBinding::Value) -> TMapValue, TMapValue: 'static + Send + Clone,

fn when_changed(&self, what: Arc<dyn Notifiable>) -> Box<dyn Releasable>

Supplies a function to be notified when this item is changed

impl<TBinding: Clone + ?Sized, TMapValue: Clone, TMapFn: Clone> Clone for MapBinding<TBinding, TMapValue, TMapFn>

fn clone(&self) -> MapBinding<TBinding, TMapValue, TMapFn>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
