Struct AnyViews 

pub struct AnyViews<V>(/* private fields */);

A type-erased container for Views collections.

AnyViews provides a uniform interface to different views collections by wrapping them in a type-erased container. This enables working with heterogeneous view collections through a common interface.

Implementations

impl<V> AnyViews<V>

where V: View,

pub fn new<C>(contents: C) -> Self

where C: Views<View = V> + 'static,

Creates a new type-erased view collection from any type implementing the Views trait.

This function wraps the provided collection in a type-erased container, allowing different view collection implementations to be used through a common interface.

Parameters

• contents - Any collection implementing the Views trait with the appropriate item type

Returns

A new AnyViews instance containing the provided collection

Trait Implementations

impl<V> Debug for AnyViews<V>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<V> From<AnyViews<V>> for SharedAnyViews<V>

fn from(value: AnyViews<V>) -> Self

Converts to this type from the input type.

impl<V> Views for AnyViews<V>

where V: View,

type Id = SelfId<Id>

The type of unique identifier for items in the collection. Must implement Hash and Ord to ensure uniqueness and ordering.

type Guard = Box<dyn WatcherGuard>

The type of guard returned when registering a watcher.

type View = V

The view type that this collection produces for each element.

fn get_id(&self, index: usize) -> Option<Self::Id>

Returns the unique identifier for the item at the specified index, or None if out of bounds.

fn get_view(&self, index: usize) -> Option<Self::View>

Returns the view at the specified index, or None if the index is out of bounds.

fn len(&self) -> usize

Returns the number of items in the collection.

fn watch( &self, range: impl RangeBounds<usize>, watcher: impl for<'a> Fn(Context<&'a [Self::Id]>) + 'static, ) -> Self::Guard

Registers a watcher for changes in the specified range of the collection.

fn is_empty(&self) -> bool

Returns true if the collection contains no elements.
