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.

UnknownEntity

An entity id was looked up but the model does not contain it.

Fields

id: EntityId

The id that resolved to nothing.

WrongEntityType

An entity was read as one IFC type but is actually another.

Fields

id: EntityId

The entity that was read.

expected: &'static str

The IFC type the caller expected.

actual: String

The IFC type actually declared.

UnsupportedEntity

The active schema does not declare the requested entity type.

Fields

schema: String

The schema’s name.

entity: &'static str

The entity type name that is undeclared.

MissingAttribute

A mandatory attribute was absent, so the value cannot be inferred.

Fields

entity: String

The entity’s IFC type.

id: EntityId

The entity that was read.

attribute: &'static str

Schema name of the attribute.

InvalidValue

An attribute was present but held the wrong kind of value.

Fields

entity: String

The entity’s IFC type.

id: EntityId

The entity that was read.

attribute: &'static str

Schema name of the attribute.

value: String

Debug-formatted offending value.

UnsupportedAttribute

The active schema declares the entity but not the requested attribute slot.

Fields

schema: String

The schema’s name.

entity: &'static str

The entity type name.

attribute: &'static str

The attribute name that is undeclared.

DanglingReference

A reference attribute pointed at an entity id the model does not contain.

Fields

source_id: EntityId

The entity holding the dangling reference.

target: EntityId

The id that resolved to nothing.

ReferenceType

A reference resolved, but the target is not the IFC type (or select member) the referencing slot requires.

Fields

target: EntityId

The entity that was read.

expected: &'static str

The IFC type (or select) the slot requires.

actual: String

The IFC type actually declared.

AuthoringInvalid

An authoring helper was given a value it cannot encode for the target attribute.

Fields

entity: &'static str

The IFC entity type being authored.

attribute: &'static str

The attribute being set.

value: String

Debug-formatted offending value.

OutOfRange

A normalized-ratio or bounded measure fell outside its required range.

Fields

entity: &'static str

The measure’s IFC type, e.g. "IfcNormalisedRatioMeasure".

id: EntityId

The entity that was read.

attribute: &'static str

Schema name of the attribute.

value: f64

The out-of-range value.

minimum: f64

The inclusive lower bound.

maximum: f64

The inclusive upper bound.

AmbiguousStyleAssignment

More than one IfcStyledItem directly assigned styles to the same representation item; cascade resolution refuses to guess a winner.

Fields

item: EntityId

The representation item with conflicting direct assignments.

count: usize

The number of conflicting IfcStyledItems found.

Trait Implementations

impl Clone for StyleError

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 StyleError

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

Formats the value using the given formatter.

impl Display for StyleError

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

Formats the value using the given formatter.

impl Error for StyleError

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 StyleError

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for StyleError
