}

Errors that may cross a substrate port boundary.

Adapters map their concrete failure modes (IO, process spawn, parse, network) onto these variants so that the core/application layers never depend on adapter-specific error types.

Variants

NotFound(String)

A requested entity (task, conversation, session) was not found.

InvalidTransition

A lifecycle transition was rejected by the FSM.

Fields

from: TaskState

State we attempted to move away from.

to: TaskState

State we attempted to move to.

ClaimConflict(String)

An atomic claim/lease could not be acquired (already held).

Engine(String)

A backing engine (CLI/process) failed.

Transport(String)

A transport (mailbox/bus) operation failed.

Store(String)

A store (persistence) operation failed.

Routing(String)

Routing could not select a target.

Serde(String)

Serialization / deserialization failed.

Io(String)

An IO error (file, pipe, process).

InvalidSchedule(String)

A schedule expression or trigger is invalid.

CycleDetected(String)

A workflow graph contains a cycle.

DuplicateWork(String)

Enqueue rejected because the body is a near-duplicate.

SchemaValidation(String)

Input failed JSON schema validation for a skill/tool.

Memory(String)

A memory port operation failed.

Process(String)

A managed subprocess operation failed.

Watcher(String)

A filesystem watcher operation failed.

CloudDispatch(String)

A cloud-dispatch adapter operation failed.

Other(String)

A catch-all for adapter-specific failures that do not fit above.

Trait Implementations

impl Debug for SubstrateError

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

Formats the value using the given formatter.

impl Display for SubstrateError

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

Formats the value using the given formatter.

impl Error for SubstrateError

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 From<Error> for SubstrateError

fn from(e: Error) -> Self

Converts to this type from the input type.
