Constraint projection or authoring failure.

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.

WrongEntityType

Entity kind differs from the requested projection.

Fields

expected: &'static str

Expected IFC entity.

actual: String

Actual IFC entity.

MissingAttribute

Required positional attribute is absent or null.

Fields

entity: &'static str

Entity kind.

id: EntityId

Entity identifier.

attribute: &'static str

Attribute name.

InvalidValue

Attribute has the wrong value shape or cardinality.

Fields

entity: &'static str

Entity kind.

id: EntityId

Entity identifier.

attribute: &'static str

Attribute name.

value: String

Diagnostic value.

UnknownEntity

Requested entity is absent.

Fields

id: EntityId

Missing identifier.

DanglingReference

Authored or projected reference does not resolve.

Fields

entity: &'static str

Relationship or record kind.

id: EntityId

Owning entity identifier.

attribute: &'static str

Attribute name.

target: EntityId

Missing target.

ReferenceType

Resolved reference is outside the declared IFC SELECT/type.

Fields

entity: &'static str

Relationship or record kind.

id: EntityId

Owning entity identifier.

attribute: &'static str

Attribute name.

target: EntityId

Referenced target.

expected: &'static str

Expected entity or SELECT.

actual: String

Actual entity kind.

Semantic

Declared WHERE-style rule failed.

Fields

entity: &'static str

Entity kind.

id: EntityId

Entity identifier.

rule: &'static str

Bounded rule name.

detail: String

Human-readable detail.

AuthoringInvalid

Draft value is invalid before staging.

Fields

entity: &'static str

Entity kind.

attribute: &'static str

Attribute or rule.

value: String

Rejected value.

AuthoringReferenceType

Draft reference is outside the required entity/SELECT.

Fields

target: EntityId

Referenced target.

expected: &'static str

Expected entity or SELECT.

actual: String

Actual entity kind.

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.

AuthoringRequired

The model’s release requires an attribute the authoring call leaves unset, such as the IFC2X3 IfcRoot.OwnerHistory or the IFC2X3 IfcRelAssociatesConstraint.Intent.

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 ConstraintError

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 ConstraintError

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

Formats the value using the given formatter.

impl Display for ConstraintError

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

Formats the value using the given formatter.

impl Error for ConstraintError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

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

impl PartialEq for ConstraintError

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
