Struct ModuleNotifier

Source 
pub struct ModuleNotifier<S> {
    broadcast: Sender<DynState>,
    module_instance: ModuleInstanceId,
    db: Database,
    _pd: PhantomData<S>,
}
Expand description

State transition notifier for a specific module instance that can only subscribe to transitions belonging to that module

Fields§

§broadcast: Sender<DynState>§module_instance: ModuleInstanceId§db: Database

Database used to load all states that happened before subscribing, see Notifier

§_pd: PhantomData<S>

S limits the type of state that can be subscribed to the one associated with the module instance

Implementations§

Source§

impl<S> ModuleNotifier<S>
where S: State,

Source

pub async fn subscribe( &self, operation_id: OperationId, ) -> BoxStream<'static, S>

Subscribe to state transitions belonging to an operation and module (module context contained in struct).

The returned stream will contain all past state transitions that happened before the subscription and are read from the database, after these the stream will contain all future state transitions. The states loaded from the database are not returned in a specific order. There may also be duplications.

Source

pub fn subscribe_all_operations(&self) -> BoxStream<'static, S>

Subscribe to all state transitions belonging to the module instance.
