Struct ObservableList 

pub struct ObservableList<T> { /* private fields */ }

A read-only list of the items of a sequence of change sets (AnonymousObservableList<T>, the result of AsObservableList).

Implementations

impl<T: Clone + PartialEq + 'static> ObservableList<T>

pub fn from_source<C: IChangeSet<T>>(source: Rc<dyn IObservable<C>>) -> Self

The list of the items of source (AnonymousObservableList(IObservable<IChangeSet<T>>)).

pub fn from_list(list: &SourceList<T>) -> Self

A read-only view of list (AnonymousObservableList(ISourceList<T>)).

Trait Implementations

impl<S: CacheChangeSetSource + Clone + PartialEq> CacheSourceListCombineEx for ObservableList<S>

type Item = <S as CacheChangeSetSource>::Item

The type of the items.

type Key = <S as CacheChangeSetSource>::Key

fn and_cache(&self) -> Rc<dyn IObservable<ChangeSet<S::Item, S::Key>>>

where Self::Item: Deref,

fn or(&self) -> Rc<dyn IObservable<ChangeSet<S::Item, S::Key>>>

where Self::Item: Deref,

The items that are in any source of the list (Or(IObservableList<..>)).

fn xor(&self) -> Rc<dyn IObservable<ChangeSet<S::Item, S::Key>>>

where Self::Item: Deref,

The items that are in exactly one source of the list (Xor(IObservableList<..>)).

fn except(&self) -> Rc<dyn IObservable<ChangeSet<S::Item, S::Key>>>

where Self::Item: Deref,

The items of the first source of the list that are in none of the others (Except(IObservableList<..>)).

impl<T> Clone for ObservableList<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
