Struct MaterialLayer 

pub struct MaterialLayer<'m> { /* private fields */ }

Borrowed projection of IFCMATERIALLAYER.

Projections handed out by a crate::MaterialView read against the release the model declares; one built with try_new has no model and reads against IFC4, as in 0.2.0.

Implementations

impl<'m> MaterialLayer<'m>

pub fn try_new(id: EntityId, entity: &'m Entity) -> MaterialResult<Self>

Wraps entity as this view after checking it is an instance of the expected IFC entity type; fails with crate::MaterialError::WrongEntityType otherwise.

Without a model there is no header to bind, so the projection reads against IFC4. Use Self::try_from_view to read the release a model declares.

pub fn try_from_view( view: MaterialView<'m>, id: EntityId, ) -> MaterialResult<Self>

Looks up id in the view’s model and projects it against the release the model declares.

Errors

crate::MaterialError::UnknownEntity when id is not in the model, and crate::MaterialError::WrongEntityType when it is another entity type.

pub fn id(self) -> EntityId

The entity id of the wrapped record.

pub fn entity(self) -> &'m Entity

The raw, untyped entity record backing this view.

pub fn schema(self) -> MaterialResult<SchemaVersion>

The release this projection reads against.

Errors

crate::MaterialError::MultipleSchemas or crate::MaterialError::UnsupportedSchema when the model’s header binds none.
