Struct TaskActor

pub struct TaskActor;

Actor that wraps and executes an async task.

Trait Implementations

impl Actor for TaskActor

type Msg = TaskActorMessage

The message type for this actor

type State = TaskFn

The type of state this actor manages internally

type Arguments = TaskFn

Initialization arguments

fn pre_start<'life0, 'async_trait>( &'life0 self, _myself: ActorRef<Self::Msg>, task: Self::Arguments, ) -> Pin<Box<dyn Future<Output = Result<Self::State, ActorProcessingErr>> + Send + 'async_trait>>

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

Invoked when an actor is being started by the system.

fn post_start<'life0, 'life1, 'async_trait>( &'life0 self, myself: ActorRef<Self::Msg>, task: &'life1 mut Self::State, ) -> Pin<Box<dyn Future<Output = Result<(), ActorProcessingErr>> + Send + 'async_trait>>

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

Invoked after an actor has started.

fn post_stop<'life0, 'life1, 'async_trait>( &'life0 self, myself: ActorRef<Self::Msg>, state: &'life1 mut Self::State, ) -> Pin<Box<dyn Future<Output = Result<(), Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

Invoked after an actor has been stopped to perform final cleanup. In the event the actor is terminated with Signal::Kill or has self-panicked, post_stop won’t be called.

fn handle<'life0, 'life1, 'async_trait>( &'life0 self, myself: ActorRef<Self::Msg>, message: Self::Msg, state: &'life1 mut Self::State, ) -> Pin<Box<dyn Future<Output = Result<(), Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

Handle the incoming message from the event processing loop. Unhandled panickes will be captured and sent to the supervisor(s)

fn handle_supervisor_evt<'life0, 'life1, 'async_trait>( &'life0 self, myself: ActorRef<Self::Msg>, message: SupervisionEvent, state: &'life1 mut Self::State, ) -> Pin<Box<dyn Future<Output = Result<(), Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

Handle the incoming supervision event. Unhandled panics will be captured and sent the the supervisor(s). The default supervision behavior is to exit the supervisor on any child exit. To override this behavior, implement this function.

fn spawn<'async_trait>( name: Option<String>, handler: Self, startup_args: Self::Arguments, ) -> Pin<Box<dyn Future<Output = Result<(ActorRef<Self::Msg>, JoinHandle<()>), SpawnErr>> + Send + 'async_trait>>

where Self: 'async_trait,

Spawn an actor of this type, which is unsupervised, automatically starting

fn spawn_linked<'async_trait>( name: Option<String>, handler: Self, startup_args: Self::Arguments, supervisor: ActorCell, ) -> Pin<Box<dyn Future<Output = Result<(ActorRef<Self::Msg>, JoinHandle<()>), SpawnErr>> + Send + 'async_trait>>

where Self: 'async_trait,

Spawn an actor of this type with a supervisor, automatically starting the actor
