Struct ActorError 

pub struct ActorError {
    pub code: ErrorCode,
    pub message: String,
    pub details: Option<String>,
    pub cause: Option<Box<ActorError>>,
}

An error originating from within an actor’s handler or lifecycle hook.

Structured error type for actor handler failures. Inspired by gRPC status codes — carries a code, message, optional details, and an error chain for causal tracing.

Fields

code: ErrorCode

The error category (e.g., Internal, InvalidArgument, NotFound).

message: String

Human-readable error description.

details: Option<String>

Optional structured details (JSON string or domain-specific data).

cause: Option<Box<ActorError>>

Causal chain — the error that caused this one.

Implementations

impl ActorError

pub fn new(code: ErrorCode, message: impl Into<String>) -> Self

Create a simple error with code and message.

pub fn internal(message: impl Into<String>) -> Self

Create an internal error (most common for unexpected failures).

pub fn with_details(self, details: impl Into<String>) -> Self

Add details to the error.

pub fn with_cause(self, cause: ActorError) -> Self

Chain a cause to this error.

Trait Implementations

impl Clone for ActorError

fn clone(&self) -> ActorError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActorError

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

Formats the value using the given formatter.

impl Display for ActorError

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

Formats the value using the given formatter.

impl Error for ActorError

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.
