A metadata model or first-increment graph-execution error.

Variants

EmptyDocumentId

A document identity cannot be empty.

CarrierSubjectMismatch

A node-local carrier must describe its enclosing node.

DocumentProvenanceIsImplicit

Document provenance comes only from the assertion owner.

EmptyAssertionSources

An explicit source list must contain at least one source.

DocumentSourceOwnerMismatch

A document source tag must name the assertion owner.

DuplicateSourceSelector(Box<AssertionKey>)

One table must not select the same assertion twice.

UnmatchedSourceSelector(Box<AssertionKey>)

The selector must name an assertion authored by this document.

SourceSelectorOwnerMismatch(Box<AssertionKey>)

The table’s owner and the selector’s owner must agree.

SourceSelectorCarrierUnsupported(Box<AssertionKey>)

Document-level source tables cannot override sidecar assertions.

AssertionNotFound

The old assertion must exist before an atomic rewrite.

AssertionCollision(Box<AssertionKey>)

Rewriting into another authored assertion would merge distinct ownership.

SourceKnowledgeConflict(Box<AssertionKey>)

Duplicate assertions cannot merge known and unknown source ownership.

UnknownSourceOwnership

Source-dependent edits require explicit ownership for every assertion in scope.

NamedGraphUnsupported

Named graph identity is modeled but cannot be inserted into this executor.

Trait Implementations

impl Eq for MetadataError

impl Error for MetadataError

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
