Struct ActorSupervisionEvent 

pub struct ActorSupervisionEvent {
    pub actor_id: ActorId,
    pub display_name: Option<String>,
    pub occurred_at: SystemTime,
    pub actor_status: ActorStatus,
    pub message_headers: Option<Flattrs>,
}

This is the local actor supervision event. Child actor will propagate this event to its parent.

Fields

actor_id: ActorId

The actor id of the child actor where the event is triggered.

display_name: Option<String>

Friendly display name, if the actor class customized it.

occurred_at: SystemTime

The time when the event is triggered.

actor_status: ActorStatus

Status of the child actor.

message_headers: Option<Flattrs>

If this event is associated with a message, the message headers.

Implementations

impl ActorSupervisionEvent

pub fn new( actor_id: ActorId, display_name: Option<String>, actor_status: ActorStatus, message_headers: Option<Flattrs>, ) -> Self

Create a new supervision event. Timestamp is set to the current time.

pub fn caused_by(&self) -> &ActorSupervisionEvent

Walk the UnhandledSupervisionEvent chain to the root-cause event — the first event whose status is not UnhandledSupervisionEvent.

pub fn actually_failing_actor(&self) -> Option<&ActorSupervisionEvent>

Walk the UnhandledSupervisionEvent chain to find the root-cause actor that originally failed.

Returns None if the event is not a failure. Always returns the leaf of the chain — the actor whose status is the root cause, even if that leaf is a non-failure (e.g. a stopped process).

pub fn is_error(&self) -> bool

This event is for a supervision error.

pub fn failure_report(&self) -> Option<String>

Produce a concise failure report. Returns None for non-failure events.

Trait Implementations

impl Clone for ActorSupervisionEvent

fn clone(&self) -> ActorSupervisionEvent

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ActorSupervisionEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ActorSupervisionEvent

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ActorSupervisionEvent

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

Formats the value using the given formatter.

impl Error for ActorSupervisionEvent

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl Handler<ActorSupervisionEvent> for ProcSupervisionCoordinator

fn handle<'life0, 'life1, 'async_trait>( &'life0 mut self, _cx: &'life1 Context<'_, Self>, msg: ActorSupervisionEvent, ) -> 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.

impl Named for ActorSupervisionEvent

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.

impl PartialEq for ActorSupervisionEvent

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ActorSupervisionEvent

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
