Required Methods

fn add_or_update_items(&mut self, items: &mut dyn Iterator<Item = T>)

Adds or replaces the items (AddOrUpdate(IEnumerable<TObject>)).

fn add_or_update_items_with( &mut self, items: &mut dyn Iterator<Item = T>, comparer: &dyn Fn(&T, &T) -> bool, )

Adds or replaces the items, leaving out an item equal to the item of its key (AddOrUpdate(IEnumerable<TObject>, IEqualityComparer<TObject>)).

fn add_or_update(&mut self, item: T)

Adds or replaces the item (AddOrUpdate(TObject)).

fn add_or_update_with(&mut self, item: T, comparer: &dyn Fn(&T, &T) -> bool)

Adds or replaces the item unless it equals the item of its key (AddOrUpdate(TObject, IEqualityComparer<TObject>)).

fn load(&mut self, items: &mut dyn Iterator<Item = T>)

Replaces every item with the items (Load).

fn lookup_item(&self, item: &T) -> Option<T>

The item of the key of item (Lookup(TObject)).

fn refresh_items(&mut self, items: &mut dyn Iterator<Item = T>)

Refreshes the items (Refresh(IEnumerable<TObject>)).

fn refresh_item(&mut self, item: &T)

Refreshes the item (Refresh(TObject)).

fn remove_items(&mut self, items: &mut dyn Iterator<Item = T>)

Removes the items (Remove(IEnumerable<TObject>)).

fn remove_item(&mut self, item: &T)

Removes the item (Remove(TObject)).

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
