Struct TestActorWithSupervisionHandling

pub struct TestActorWithSupervisionHandling;

A test actor that handles supervision events. It should be the parent of TestActor who can panic or cause a SIGSEGV.

Trait Implementations

impl Actor for TestActorWithSupervisionHandling

type Params = ()

The type of initialization parameters accepted by this actor.

fn new<'async_trait>( _params: Self::Params, ) -> Pin<Box<dyn Future<Output = Result<Self, Error>> + Send + 'async_trait>>

where Self: 'async_trait,

Creates a new actor instance given its instantiation parameters.

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

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

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

where 'life0: 'async_trait, 'life1: 'async_trait, Self: '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 spawn<'life0, 'async_trait>( cx: &'life0 (impl Actor + 'async_trait), params: Self::Params, ) -> Pin<Box<dyn Future<Output = Result<ActorHandle<Self>, Error>> + Send + 'async_trait>>

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

Spawn a child actor, given a spawning capability (usually given by Instance). The spawned actor will be supervised by the parent (spawning) actor.

fn spawn_detached<'async_trait>( params: Self::Params, ) -> Pin<Box<dyn Future<Output = Result<ActorHandle<Self>, Error>> + Send + 'async_trait>>

where Self: 'async_trait,

Spawns this actor in a detached state, handling its messages in a background task. The returned handle is used to control the actor’s lifecycle and to interact with it.

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_undeliverable_message<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Instance<Self>, envelope: 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.

impl Binds<TestActorWithSupervisionHandling> for TestActorWithSupervisionHandling

fn bind(ports: &Ports<Self>)

Bind ports in this actor.

impl Debug for TestActorWithSupervisionHandling

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

Formats the value using the given formatter.

impl Default for TestActorWithSupervisionHandling

fn default() -> TestActorWithSupervisionHandling

Returns the “default value” for a type.

impl Handler<ActorSupervisionEvent> for TestActorWithSupervisionHandling

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

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

Handle the next M-typed message.

impl Named for TestActorWithSupervisionHandling

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

The globally unique port for this type. Typed ports are in the range of 1<<63..1<<64-1.

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.
