Implementations

impl FerroDictionaryExtensions

pub fn for_each_item<K, V, D>( collection: &D, added: impl Fn(&K, &V) + 'static, removed: impl Fn(&K, &V) + 'static, reset: impl Fn() + 'static, weak_subscription: bool, ) -> Rc<dyn IDisposable>

where K: Clone + 'static, V: Clone + 'static, D: IFerroReadOnlyDictionary<K, V> + WeakEventSender,

Invokes an action for each item in a collection and subsequently each item added or removed from the collection.

added is called initially for each item in the collection and subsequently for each item added to the collection, with the key and the value; removed for each item removed from the collection; reset when the collection is reset, which is followed by calls to added for each item present in the collection after the reset. weak_subscription indicates if a weak subscription should be used to track changes to the collection (held by the returned disposable, see FerroListExtensions::for_each_item_indexed). Returns a disposable used to terminate the subscription.
