Enum TemplateError 

#[non_exhaustive]
pub enum TemplateError {
    Release(ExactPropertyError),
    NoTemplates {
        schema: SchemaVersion,
    },
    MissingEntity {
        id: EntityId,
    },
    NotATemplate {
        id: EntityId,
        type_name: String,
    },
}

Why property templates could not be read or checked against the release a model declares.

Distinct from PropertyAnomaly: an anomaly is a malformed fact inside a file that can still be read; this refuses the whole request.

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.

Release(ExactPropertyError)

The model cannot be bound to one release, for the reason exact_schema gives: STEP diagnostics, no or several FILE_SCHEMA entries, or an unsupported one.

NoTemplates

The declared release defines no property templates.

IfcPropertySetTemplate and its property templates are new in IFC4; IFC2X3 TC1 declares none of them, so nothing in such a file can be a template.

Fields

schema: SchemaVersion

The release the header declares.

MissingEntity

The entity is not in the model.

Fields

id: EntityId

The id named by the caller.

NotATemplate

The entity is not the kind of template asked for.

Fields

id: EntityId

The entity.

type_name: String

Its IFC type name.

Trait Implementations

impl Clone for TemplateError

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 TemplateError

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

Formats the value using the given formatter.

impl Eq for TemplateError

impl Error for TemplateError

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 TemplateError

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

Equality operator ==.

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

Inequality operator !=.
