}

Errors produced by the workloop services.

Variants

Spec(WorkloopSpecError)

A declaration was invalid at the engine boundary (no assumed defaults: cadence, tolerance, and retention are declared or refused).

Store(StoreError)

The workloop store refused or failed an operation.

Durability(DurabilityError)

The single-Recorder append path failed.

NotRegistered

A loop id was expected to be registered and was not.

Fields

loop_id: WorkflowId

The unregistered loop.

AlreadyRegistered

A loop was already registered under this id.

Fields

loop_id: WorkflowId

The already-registered loop.

ZeroSweepInterval

The sweep interval was zero: the sweeper’s clock is a declared value, never defaulted, and a zero interval is a busy-spin, not a cadence.

UnrepresentableDuration

A declared duration could not be represented on the engine clock.

Fields

reason: String

What overflowed.

UndeclaredInvariant

A health sample named an invariant the loop never declared.

Fields

loop_id: WorkflowId

The loop the sample was fed to.

invariant: String

The undeclared invariant name.

Engine

The engine seam refused an operation (recording, waking, spawning).

Fields

reason: String

Human-readable seam failure reason.

Trait Implementations

impl Debug for WorkloopError

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

Formats the value using the given formatter.

impl Display for WorkloopError

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

Formats the value using the given formatter.

impl Error for WorkloopError

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.
