Invalid workflow definition.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EmptyName

The workflow name is blank.

InvalidStepId(String)

A step identifier is invalid.

DuplicateStep(StepId)

The same step identifier occurs more than once.

NoSteps

The workflow has no executable nodes.

InvalidVersion

Version zero is reserved for invalid or unversioned definitions.

InvalidTimerDuration

A durable timer duration is invalid.

InvalidSignalName

An external signal name is invalid.

InvalidInterruptPrompt

A human-review prompt is blank or exceeds its durable limit.

TooFewParallelBranches(StepId)

A parallel group requires at least two branches.

TooFewRaceBranches(StepId)

A first-success race requires at least two branches.

InvalidParallelBranchId(String)

A parallel branch identifier is invalid.

DuplicateParallelBranch

A parallel branch identifier occurs more than once in its group.

Fields

step: StepId

Parallel group identity.

branch: StepId

Duplicate branch identity.

UnsafeRaceCapability

A race branch requested a capability that may mutate external state.

Fields

step: StepId

Race node identity.

branch: StepId

Unsafe branch identity.

capability: String

Rejected capability name.

Trait Implementations

impl Eq for WorkflowBuildError

impl Error for WorkflowBuildError

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
