Struct SystemHandle 

pub struct SystemHandle { /* private fields */ }

Contains the “metadata” of the system, including information about the registry of actors currently existing within the system.

Implementations

impl SystemHandle

pub fn shutdown(&self) -> Result<(), ActorError>

Stops all actors spawned by this system.

pub fn subscribe_recipient<M: 'static, E: Event + Into<M>>( &self, recipient: Recipient<M>, )

Subscribe given recipient to events of type E. See Context::subscribe().

pub fn subscribe_and_receive_latest<M: 'static, E: Event + Into<M>>( &self, recipient: Recipient<M>, ) -> Result<(), SendError>

Subscribe given recipient to events of type E and send the last cached event to it. See Context::subscribe_and_receive_latest().

pub fn publish<E: Event>(&self, event: E) -> Result<(), PublishError>

Publish an event. All actors that have previously subscribed to the type will receive it.

The event will be also cached. Actors that will subscribe to the type in future may choose to receive the last cached event upon subscription.

When sending to some subscriber fails, others are still tried and vec of errors is returned. For direct, non-Clone or high-throughput messages please use Addr or Recipient.

pub fn is_running(&self) -> bool
