Enum EngineError 

pub enum EngineError {
    ComponentNotFound(ComponentId),
    ChannelNotFound(ChannelId),
    NoTarget,
    SendFailed(String),
    ChannelClosed,
    NotRunning,
    Timeout(RequestId),
    ComponentFailed(String),
    NoSubscriber(EventCategory),
    PackageFailed(String),
    PackageNotSupported(ComponentId),
}

Engine layer error.

Represents failures within the Engine runtime and EventBus. Implements ErrorCode for standardized error handling.

Example

use orcs_runtime::EngineError;
use orcs_types::ErrorCode;

let err = EngineError::NoTarget;
assert_eq!(err.code(), "ENGINE_NO_TARGET");
assert!(!err.is_recoverable());

Variants

ComponentNotFound(ComponentId)

Component not found in EventBus registry.

ChannelNotFound(ChannelId)

Channel not found for event injection.

NoTarget

Request target is required but not specified.

SendFailed(String)

Failed to send message to component.

ChannelClosed

Component channel was closed unexpectedly.

NotRunning

Engine is not running.

Timeout(RequestId)

Request timed out waiting for response.

ComponentFailed(String)

Component returned an error.

NoSubscriber(EventCategory)

No subscriber for the requested category.

PackageFailed(String)

Package operation failed.

PackageNotSupported(ComponentId)

Component does not support packages.

Trait Implementations

impl Clone for EngineError

fn clone(&self) -> EngineError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Error for EngineError

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 ErrorCode for EngineError

fn code(&self) -> &'static str

Returns a machine-readable error code.

fn is_recoverable(&self) -> bool

Returns whether the error is recoverable.

impl From<EngineError> for AppError

fn from(source: EngineError) -> Self

Converts to this type from the input type.
