A refused authoring request.

Distinct from PropertyAnomaly, which reports what a FILE got wrong. These say the CALLER asked for something the schema does not allow, and are returned before anything is staged so a rejected edit never reaches a transaction.

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.

MissingEntity

The entity is not in the model.

Fields

id: EntityId

The id named by the caller.

NotAQuantity

The entity is not a simple quantity type.

Fields

id: EntityId

The entity.

type_name: String

What it actually is.

NotAQuantitySet

The entity is not an IfcElementQuantity.

Fields

id: EntityId

The entity.

type_name: String

What it actually is.

AuthoringInvalid

An authored attribute value is not valid for its slot.

Raised before staging, so a rejected draft never reaches the model.

Fields

entity: &'static str

The entity type being authored.

attribute: &'static str

The attribute that failed.

value: String

The offending value, rendered for the message.

MultipleSchemas

The model’s header declares several schemas; authoring binds to exactly one release.

Fields

schemas: usize

Number of FILE_SCHEMA declarations.

UnsupportedSchema

The model’s header declares one schema with no bundled table, so no layout can be trusted.

Fields

schema: String

The FILE_SCHEMA token as written.

EntityNotInSchema

The model’s release does not declare this entity, such as IfcQuantityNumber (IFC4X3 only) in an IFC2X3 or IFC4 model.

Fields

entity: &'static str

The entity type, in schema casing.

schema: SchemaVersion

The release the model declares.

AuthoringNotInSchema

An authoring call supplied a value for an attribute the model’s release does not declare, such as a Formula for an IFC2X3 quantity. It is refused rather than dropped.

Fields

entity: &'static str

The entity type, in schema casing.

attribute: &'static str

The attribute.

schema: SchemaVersion

The release the model declares.

MalformedEntitySlots

The record to edit does not have the attribute count its release declares, so no slot in it can be trusted.

Fields

id: EntityId

The record.

type_name: String

Its type.

expected: usize

Attribute count the release declares.

actual: usize

Attribute count the record has.

AuthoringRequired

The model’s release requires an attribute the authoring call leaves unset, such as the IFC2X3 IfcRoot.OwnerHistory (#191). It is refused rather than written as $; the *_with_owner_history writers take the IfcOwnerHistory IFC2X3 needs.

Fields

entity: &'static str

The entity type being authored.

attribute: &'static str

The required attribute, as the release names it.

schema: SchemaVersion

The release the model declares.

Trait Implementations

impl Clone for PropertyError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PropertyError

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

impl Eq for PropertyError

impl Error for PropertyError

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

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

Provides type-based access to context intended for error reports.

impl PartialEq for PropertyError

fn eq(&self, other: &Self) -> bool

Equality operator ==.
