Struct ActorSpawner 

pub struct ActorSpawner;

Remote actor that accepts dynamic remote spawn requests.

Trait Implementations

impl Accepts<IntrospectMessage> for ActorSpawner

impl Accepts<SpawnActor> for ActorSpawner

where SpawnActor: RemoteMessage,

impl Actor for ActorSpawner

fn init<'life0, 'life1, 'async_trait>( &'life0 mut self, this: &'life1 Instance<Self>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Initialize the actor, after the runtime has been fully initialized. Init thus provides a mechanism by which an actor can reliably and always receive some initial event that can be used to kick off further (potentially delayed) processing.

fn handle_stop<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, this: &'life1 Instance<Self>, mode: StopMode, reason: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Handle a stop request from the runtime.

fn cleanup<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, _this: &'life1 Instance<Self>, _err: Option<&'life2 ActorError>, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Cleanup things used by this actor before shutting down. Notably this function is async and allows more complex cleanup. Simpler cleanup can be handled by the impl Drop for this Actor. If err is not None, it is the error that this actor is failing with. Any errors returned by this function will be logged and ignored. If err is None, any errors returned by this function will be propagated as an ActorError. This function is not called if there is a panic in the actor, as the actor may be in an indeterminate state. It is also not called if the process is killed, there is no atexit handler or signal handler.

fn spawn_server_task<F>(future: F) -> JoinHandle<<F as Future>::Output>

where F: Future + Send + 'static, <F as Future>::Output: Send + 'static,

This method is used by the runtime to spawn the actor server. It can be used by actors that require customized runtime setups (e.g., dedicated actor threads), or want to use a custom tokio runtime.

fn handle_supervision_event<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, _this: &'life1 Instance<Self>, event: &'life2 ActorSupervisionEvent, ) -> Pin<Box<dyn Future<Output = Result<bool, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Handle actor supervision event. Return `Ok(true)`` if the event is handled here.

fn handle_delivery_failure_event<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Instance<Self>, undeliverable: Undeliverable<MessageEnvelope>, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Default delivery-failure event handling behavior.

fn handle_undeliverable_message<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Instance<Self>, reason: UndeliverableReason, undeliverable: Undeliverable<MessageEnvelope>, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Default undeliverable message handling behavior.

fn handle_invalid_reference<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Instance<Self>, invalid: InvalidReference, undeliverable: Undeliverable<MessageEnvelope>, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Default invalid-reference handling behavior.

fn handle_expired_delivery<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Instance<Self>, expired: ExpiredDelivery, undeliverable: Undeliverable<MessageEnvelope>, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Default expired-delivery handling behavior.

fn display_name(&self) -> Option<String>

If overridden, we will use this name in place of the ActorAddr for talking about this actor in supervision error messages.

impl Binds<ActorSpawner> for ActorSpawner

where SpawnActor: RemoteMessage, ActorSpawner: Handler<SpawnActor>,

fn bind(ports: &HandlerPorts<Self>)

Bind ports in this actor.

impl Debug for ActorSpawner

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

Formats the value using the given formatter.

impl Default for ActorSpawner

fn default() -> ActorSpawner

Returns the “default value” for a type.

impl Handler<SpawnActor> for ActorSpawner

fn handle<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Context<'_, Self>, message: SpawnActorMessage, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Handle the next M-typed message.

fn message_status_reporting() -> MessageStatusReporting

Select which layer reports the message’s terminal telemetry status.

impl Named for ActorSpawner

fn typename() -> &'static str

The globally unique type name for the type. This should typically be the fully qualified Rust name of the type.

fn typehash() -> u64

A globally unique hash for this type. TODO: actually enforce perfect hashing

fn typeid() -> TypeId

The TypeId for this type. TypeIds are unique only within a binary, and should not be used for global identification.

fn port() -> u64

A globally unique numeric identifier for this type.

fn arm(&self) -> Option<&'static str>

If the named type is an enum, this returns the name of the arm of the value self.

unsafe fn arm_unchecked(self_: *const ()) -> Option<&'static str>

An unsafe version of ‘arm’, accepting a pointer to the value, for use in type-erased settings.
