Struct ActorId 

pub struct ActorId(/* private fields */);

Unique identifier for a registered actor.

Returned by Supervisor::add_actor. Use ActorId to:

• Identify actors in event metadata (sender information)
• Reference actors in test harness assertions
• Track event flow between specific actors

ActorId is cheap to clone and safe to serialize. Equality works correctly across serialization boundaries (uses string comparison with a fast-path for pointer equality when IDs share the same allocation).

Example

let producer = sup.add_actor("producer", |ctx| Producer::new(ctx), &[DefaultTopic])?;
let consumer = sup.add_actor("consumer", |ctx| Consumer::new(ctx), &[DefaultTopic])?;

// Use in test harness
let mut test = Harness::new(&mut sup).await;
test.send_as(&producer, MyEvent::Data(42)).await?;
assert!(test.actor(&consumer).events_received() > 0);

// Access sender from event metadata
let sender: &ActorId = envelope.meta().actor_id();

Creating IDs for External Systems

For bridge actors that receive events from external sources (IPC, WebSocket), use ActorId::new() to create identifiers for those sources.

Implementations

impl ActorId

pub fn new(id: &str) -> Self

Create an actor ID from a string name.

pub fn as_str(&self) -> &str

Returns the string representation of this actor ID.

Trait Implementations

impl AsRef<str> for ActorId

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ActorId

fn clone(&self) -> ActorId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActorId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ActorId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ActorId

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

Formats the value using the given formatter.

impl From<&str> for ActorId

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for ActorId

fn from(s: String) -> Self

Converts to this type from the input type.

impl Hash for ActorId

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ActorId

fn cmp(&self, other: &ActorId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ActorId

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 PartialOrd for ActorId

fn partial_cmp(&self, other: &ActorId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for ActorId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
