Struct BindableDictionary 

pub struct BindableDictionary<K: Eq + Hash + Clone + Display + 'static, V: PropertyValue> { /* private fields */ }

A notifying dictionary that bindings can index into (Items[key]): a FerroDictionary together with the untyped change event that binding indexers subscribe to.

As a model object it has identity equality.

Implementations

impl<K: Eq + Hash + Clone + Display + 'static, V: PropertyValue> BindableDictionary<K, V>

pub fn new(entries: impl IntoIterator<Item = (K, V)>) -> Rc<Self>

Creates a dictionary with the given entries.

pub fn items(&self) -> &FerroDictionary<K, V>

The typed dictionary.

Trait Implementations

impl<K: Eq + Hash + Clone + Display + 'static, V: PropertyValue> IBindableIndexer for BindableDictionary<K, V>

fn index_parameter_types(&self) -> Vec<ValueType>

The types of the index parameters, in order.

fn value_type(&self) -> ValueType

The type of the values of the indexer.

fn get( &self, arguments: &[BoxedValue], ) -> Result<Option<BoxedValue>, BindingError>

Reads the value at arguments, which hold exactly the declared parameter types. An error is what the getter of a managed indexer throws: a missing key, an index out of range.

fn set( &self, arguments: &[BoxedValue], value: Option<&BoxedValue>, ) -> Result<bool, BindingError>

Writes the value at arguments. Returns Ok(false) if the indexer has no setter.

fn can_set(&self) -> bool

Whether the indexer has a setter.

impl<K: Eq + Hash + Clone + Display + 'static, V: PropertyValue> INotifyCollectionChanged for BindableDictionary<K, V>

fn collection_changed(&self) -> &Event<CollectionChange>

The event raised when the collection changes.

impl<K: Eq + Hash + Clone + Display + 'static, V: PropertyValue> INotifyPropertyChanged for BindableDictionary<K, V>

fn property_changed(&self) -> &Event<str>

The event raised when a property value changes.

fn as_notify_property_changing(&self) -> Option<&dyn INotifyPropertyChanging>

The object as INotifyPropertyChanging, when it also raises the event of a property that is about to change; None by default.

impl<K: Eq + Hash + Clone + Display + 'static, V: PropertyValue> PartialEq for BindableDictionary<K, V>

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
