Errors encountered during construction of a Validation Schema

Variants

ParseJson(Error)

Errors loading and parsing schema files

ActionTransitiveClosureError(String)

Errors occurring while computing or enforcing transitive closure on action id hierarchy.

EntityTransitiveClosureError(String)

Errors occurring while computing or enforcing transitive closure on entity type hierarchy.

UnsupportedSchemaFeature(String)

Error generated when processing a schema file that uses features which are not yet supported by the implementation.

UndeclaredEntityTypes(HashSet<String>)

Undeclared entity type(s) used in an entity type’s memberOf field or an action’s appliesTo fields.

UndeclaredActions(HashSet<String>)

Undeclared action(s) used in an action’s memberOf field.

UndeclaredCommonType(HashSet<String>)

Undeclared type used in entity or context attributes.

DuplicateEntityType(String)

Duplicate specifications for an entity type. Argument is the name of the duplicate entity type.

DuplicateAction(String)

Duplicate specifications for an action. Argument is the name of the duplicate action.

DuplicateCommonType(String)

Duplicate specifications for a reusable common type. Argument is the name of the duplicate type.

CycleInActionHierarchy

Cycle in the schema’s action hierarchy.

EntityTypeParse(ParseErrors)

Parse errors occurring while parsing an entity type.

NamespaceParse(ParseErrors)

Parse errors occurring while parsing a namespace identifier.

CommonTypeParseError(ParseErrors)

Parse errors occurring while parsing a common type identifier.

ExtensionTypeParse(ParseErrors)

Parse errors occurring while parsing an extension type.

ActionEntityTypeDeclared

The schema file included an entity type Action in the entity type list. The Action entity type is always implicitly declared, and it cannot currently have attributes or be in any groups, so there is no purposes in adding an explicit entry.

ActionEntityAttributes(Vec<String>)

One or more action entities are declared with attributes lists, but action entities cannot have attributes.

ContextOrShapeNotRecord

An action context or entity type shape was declared to have a type other than Record.

ActionEntityAttributeEmptySet

An Action Entity (transitively) has an attribute that is an empty set

ActionEntityAttributeUnsupportedType

An Action Entity (transitively) has an attribute of unsupported type (ExprEscape, EntityEscape or ExtnEscape)

Trait Implementations

impl Debug for SchemaError

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

Formats the value using the given formatter.

impl Display for SchemaError

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

Formats the value using the given formatter.

impl Error for SchemaError

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
