Failure to construct a bounded restart 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.

ZeroStartLimit

A start limit of zero can never start its step.

EmptyToken

A required token was empty.

Fields

kind: DefinitionTokenKind

Rejected token category.

TokenTooLong

A token exceeded its UTF-8 byte bound.

Fields

kind: DefinitionTokenKind

Rejected token category.

max_bytes: usize

Maximum accepted byte length.

SurroundingWhitespace

A token had leading or trailing whitespace.

Fields

kind: DefinitionTokenKind

Rejected token category.

ControlCharacter

A token contained a control character.

Fields

kind: DefinitionTokenKind

Rejected token category.

ManifestEncoding

The canonical manifest could not be encoded.

ManifestTooLarge

The canonical manifest exceeded its durable bound.

Fields

max_bytes: usize

Maximum accepted byte length.

UpgradeSelfEdge

A directed edge pointed from a definition to itself.

EmptyStepMapping

A directed edge omitted its durable step mapping.

DuplicateSourceStep

A source step appeared more than once.

DuplicateTargetStep

Two source steps mapped to the same target step.

DeliveryModeMismatch

A step’s fault runtime declared a different delivery mode than its restart contract.

CompatibilityLowering

A one-step wrapper could not be lowered into its compatibility plan.

The framework derives the compatibility graph from values it has already validated, so this variant reports a framework invariant rather than an application mistake.

RuntimeStreamNotDeclared

A runtime ItemStream was registered under a namespace this definition’s ChunkComponentRevisions does not declare.

Fields

namespace: ComponentStreamIdentity

The undeclared runtime namespace.

DeclaredStreamMissingRuntime

A declared stream revision has no matching runtime ItemStream registration.

Fields

namespace: ComponentStreamIdentity

The declared namespace with no runtime registration.

DuplicateRuntimeStream

The same namespace was registered as a runtime ItemStream more than once.

Fields

namespace: ComponentStreamIdentity

The namespace registered more than once.

NonRestartableStream

A registered ItemStream declares RestartabilityDeclaration::NotRestartable, which prevents its owning chunk step from claiming restartability regardless of reader-checkpoint presence.

Fields

namespace: ComponentStreamIdentity

The namespace whose stream cannot honestly claim restartability.

CompletionPolicyFingerprintPanic

An installed completion policy’s fingerprint() panicked while its configuration was being folded into the chunk definition’s restart-relevant revisions.

fingerprint() is an application-supplied callback (every built-in policy’s own implementation cannot panic), so a definition cannot be constructed from one that does – this is reported the same way any other definition-construction failure is, rather than unwinding out of a constructor with a Result return type.

CompletionPolicyRevisionMismatch

A chunk step’s live completion-policy fingerprint does not match the completion-policy revision already declared in the ChunkComponentRevisions a compiled flow node was bound against.

Unlike a standalone chunk job (which builds its compiled plan and runtime step from the same call, so it can fold a completion policy’s fingerprint in automatically), a flow node is bound to a plan that was already compiled from bare ChunkComponentRevisions – before any concrete step, or its installed policy, existed. The caller must declare the matching revision up front (the same way a stream revision is declared up front and validated against its runtime registration) rather than relying on it being computed automatically.
