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 did not have the expected IFC type.

Fields

expected: &'static str

IFC type name expected at this position.

actual: String

IFC type name actually found.

MissingAttribute

A required attribute was unset ($ or *) or absent.

Fields

entity: &'static str

IFC entity type of the offending instance.

id: EntityId

Id of the offending instance.

attribute: &'static str

Name of the missing attribute.

InvalidValue

An attribute was present but failed to decode as its expected shape.

Fields

entity: &'static str

IFC entity type of the offending instance.

id: EntityId

Id of the offending instance.

attribute: &'static str

Name of the invalid attribute.

value: String

Debug rendering of the offending value.

UnknownEntity

A referenced entity id does not exist in the model.

Fields

id: EntityId

Id that could not be resolved.

DanglingReference

An attribute reference points at an id that is not present in the model.

Fields

entity: &'static str

IFC entity type holding the dangling reference.

id: EntityId

Id of the entity holding the dangling reference.

attribute: &'static str

Name of the attribute holding the dangling reference.

target: EntityId

Id that could not be resolved.

ReferenceType

An attribute reference resolves but the target entity has the wrong type for its select.

Fields

entity: &'static str

IFC entity type holding the mistyped reference.

id: EntityId

Id of the entity holding the mistyped reference.

attribute: &'static str

Name of the attribute holding the mistyped reference.

target: EntityId

Id of the mistyped target.

expected: &'static str

Select or type name the target was expected to satisfy.

actual: String

IFC type name the target actually has.

Cycle

Following ReferencedSource links revisited an already-seen entity.

Fields

path: Vec<EntityId>

Entity ids on the cycle, in traversal order.

BudgetExceeded

Hierarchy traversal exceeded the caller-supplied node or depth budget.

Fields

max_depth: usize

Maximum edge depth allowed.

max_nodes: usize

Maximum number of nodes allowed.

AmbiguousType

An occurrence object is related to more than one IfcRelDefinesByType type.

Fields

object: EntityId

The occurrence object with the ambiguous type assignment.

count: usize

Number of types the object was found related to.

AuthoringInvalid

A draft value failed schema validation before staging.

Fields

entity: &'static str

IFC entity type being authored.

attribute: &'static str

Name of the offending attribute.

value: String

Description of why the value is invalid.

AuthoringReferenceType

A draft reference resolves to a staged or committed entity of the wrong type.

Fields

target: EntityId

Id of the mistyped reference target.

expected: &'static str

Select or type name the target was expected to satisfy.

actual: String

IFC type name the target actually has.

Trait Implementations

impl Clone for ClassificationError

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 ClassificationError

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

Formats the value using the given formatter.

impl Display for ClassificationError

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

Formats the value using the given formatter.

impl Error for ClassificationError

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 ClassificationError

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

Equality operator ==.

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

Inequality operator !=.
