A refused construction.

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 requested entity is not present in the model snapshot.

Fields

id: EntityId

The missing entity id.

UnknownEntity

The schema does not declare this entity type.

Reported rather than ignored: silently accepting an unknown type is how a typo becomes a file other tools reject.

Fields

entity: String

The requested type name.

UnknownAttribute

The schema declares the entity, but not this attribute.

Fields

entity: String

The entity being built.

attribute: String

The attribute name the caller supplied.

known: Vec<String>

Attribute names the schema does declare, in positional order.

MissingRequired

A required (non-OPTIONAL) attribute was never set.

Fields

entity: String

The entity being built.

attribute: String

The unset attribute.

DuplicateAttribute

The same attribute was set twice.

A silent overwrite hides a copy-paste error in the caller.

Fields

entity: String

The entity being built.

attribute: String

The attribute set more than once.

TypeMismatch

The value does not match the attribute’s declared type.

Fields

entity: String

The entity being built.

attribute: String

The attribute that was set.

expected: String

The type the schema declares.

found: String

What the supplied value actually was.

AggregateMismatch

A scalar was supplied where the schema declares an aggregate, or vice versa.

Fields

entity: String

The entity being built.

attribute: String

The attribute that was set.

expected_aggregate: bool

Whether the schema declares an aggregate.

InvalidGlobalId

A GlobalId was supplied that is not a valid 22-character IFC GUID.

Fields

entity: String

The entity being built.

found: String

The rejected text.

DerivedAttribute

A slot the schema derives for this entity was given a value.

A subtype can redeclare an inherited attribute as DERIVEd, as IfcSIUnit does with Dimensions. Part 21 writes such a slot as *: neither a value nor $ is valid there. The builder writes * itself when the slot is left unset.

Fields

entity: String

The entity being built or edited.

attribute: String

The derived attribute.

found: String

What was supplied instead of *.

NotDerived

* was supplied for a slot the schema does not derive for this entity.

Fields

entity: String

The entity being built or edited.

attribute: String

The attribute that was set.

ArityMismatch

An existing entity does not have the arity declared by the schema.

Fields

entity: String

The entity being edited.

expected: usize

Number of attributes declared by the schema.

found: usize

Number of attributes present in the model.

ValueForm

A value of the declared type, written in the form ISO 10303-21 does not use for it.

A typed parameter (IFCAREAMEASURE(12.5)) is written exactly where the declared type is a SELECT, which needs it to say which member the value is (§12.1.8); everywhere else the bare value is written (§12.1.6, §12.1.7). A wrapper naming a different type than the one declared is a TypeMismatch instead.

Fields

entity: String

The entity being built or edited.

attribute: String

The attribute that was set.

declared: String

The declared type, or the element type of a declared aggregate.

typed_required: bool

Whether the declared type requires the typed form: true for a bare value in a SELECT slot, false for a wrapper elsewhere.

found: String

What the supplied value actually was.

Trait Implementations

impl Clone for AuthorError

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 AuthorError

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

Formats the value using the given formatter.

impl Display for AuthorError

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

Formats the value using the given formatter.

impl Eq for AuthorError

impl Error for AuthorError

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 AuthorError

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

Equality operator ==.

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

Inequality operator !=.
