Struct BindRef 

pub struct BindRef<Target> { /* private fields */ }

A BindRef references another binding without needing to know precisely what kind of binding it is. It is read-only, so mostly useful for passing a binding around, particularly for computed bindings. Create one with BindRef::from(binding).

Cloning a BindRef will create another reference to the same binding.

Implementations

impl<TValue> BindRef<TValue>

pub fn new<Binding>(binding: &Binding) -> BindRef<TValue>

where Binding: 'static + Clone + Bound<Value = TValue>,

Creates a new BindRef from a reference to an existing binding

pub fn from_arc<Binding>(binding_ref: Arc<Binding>) -> BindRef<TValue>

where Binding: 'static + Bound<Value = TValue>,

Creates a new BindRef from an existing binding

Trait Implementations

impl<TValue> Bound for BindRef<TValue>

type Value = TValue

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<Value> Changeable for BindRef<Value>

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

Supplies a function to be notified when this item is changed

impl<Value> Clone for BindRef<Value>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
