Struct ResultSet 

pub struct ResultSet<R: View>(/* private fields */);

View-typed ResultSet

Implementations

impl<R: View> ResultSet<R>

pub fn by_id(&self, id: &EntityId) -> Option<R>

impl<E: View> ResultSet<E>

pub fn iter(&self) -> ResultSetIter<E>

Methods from Deref<Target = EntityResultSet<Entity>>

pub fn write(&self) -> ResultSetWrite<'_, E>

Begin a write operation for atomic changes to the resultset All mutations happen through the returned write guard A single notification is sent when the guard is dropped (if changes were made)

pub fn read(&self) -> ResultSetRead<'_, E>

Get a read guard for consistent read-only access to the resultset

pub fn set_loaded(&self, loaded: bool)

pub fn is_loaded(&self) -> bool

pub fn clear(&self)

pub fn keys(&self) -> EntityResultSetKeyIterator

Get an iterator over entity IDs without cloning entities

pub fn contains_key(&self, id: &EntityId) -> bool

Check if an entity with the given ID exists

pub fn by_id(&self, id: &EntityId) -> Option<E>

pub fn len(&self) -> usize

pub fn get_limit(&self) -> Option<usize>

Get the current limit for this result set

pub fn wrap<R: View>(&self) -> ResultSet<R>

Trait Implementations

impl<E: View> Clone for ResultSet<E>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<R: Debug + View> Debug for ResultSet<R>

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

Formats the value using the given formatter.

impl<E: View> Default for ResultSet<E>

fn default() -> Self

Returns the “default value” for a type.

impl<R: View> Deref for ResultSet<R>

type Target = EntityResultSet

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<E: View + Clone + 'static> Get<Vec<E>> for ResultSet<E>

fn get(&self) -> Vec<E>

impl<E: View + Clone> IntoIterator for &ResultSet<E>

type Item = E

The type of the elements being iterated over.

type IntoIter = ResultSetIter<E>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<E: View + Clone> IntoIterator for ResultSet<E>

type Item = E

The type of the elements being iterated over.

type IntoIter = ResultSetIter<E>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<E: View + Clone + 'static> Peek<Vec<E>> for ResultSet<E>

fn peek(&self) -> Vec<E>

impl<R: View> Signal for ResultSet<R>

fn listen(&self, listener: Listener) -> ListenerGuard

Listen to changes to this signal with a listener function Takes an Arc-wrapped closure for efficiency - wrap your closure with Arc::new(|| { … })

fn broadcast_id(&self) -> BroadcastId

Get the broadcast identifier for this signal. Multiple signals may return the same broadcast_id if they share a broadcast. The broadcast_id remains valid as a deduplication key as long as any ListenerGuard for that broadcast exists.

impl<E: View + Clone + 'static> Subscribe<Vec<E>> for ResultSet<E>

fn subscribe<F>(&self, listener: F) -> SubscriptionGuard

where F: IntoSubscribeListener<Vec<E>>,

Subscribe to changes with a listener that receives the new value
