EntityStream

unifly_core::stream

Struct EntityStream 

Source 
pub struct EntityStream<T: Clone + Send + Sync + 'static> { /* private fields */ }
Expand description

A subscription to a collection of entities.

Provides both point-in-time snapshot access and reactive change notification via the changed() method or by converting to a Stream.

Implementations§

Source§

impl<T: Clone + Send + Sync + 'static> EntityStream<T>

Source

pub fn current(&self) -> &Arc<Vec<Arc<T>>>

Get the snapshot captured at creation time.

Source

pub fn latest(&self) -> Arc<Vec<Arc<T>>>

Get the latest snapshot (may have changed since creation).

Source

pub async fn changed(&mut self) -> Option<Arc<Vec<Arc<T>>>>

Wait for the next change, returning the new snapshot. Returns None if the sender (DataStore) has been dropped.

Source

pub fn into_stream(self) -> EntityWatchStream<T>

Convert into a Stream for use with StreamExt combinators.
