Struct StructuralAction 

pub struct StructuralAction<'m, 's> { /* private fields */ }

Borrowed projection of an IfcStructuralAction (point, curve/linear, or surface/planar).

The IFC2X3-only varying subtypes IfcStructuralLinearActionVarying and IfcStructuralPlanarActionVarying classify as ActionKind::Curve and ActionKind::Surface; StructuralAction::is_varying tells them apart and StructuralAction::subsequent_applied_loads reads their load list.

Implementations

impl<'m, 's> StructuralAction<'m, 's>

pub fn is_varying(&self) -> bool

Whether the entity is an IFC2X3 IfcStructuralLinearActionVarying or IfcStructuralPlanarActionVarying.

Always false under IFC4 and IFC4X3, which declare neither entity.

pub fn varying_applied_load_location( &self, ) -> StructuralResult<Option<EntityId>>

VaryingAppliedLoadLocation, the IfcShapeAspect locating the varying loads along the activity.

None for a non-varying action and under IFC4/IFC4X3. Fails with StructuralError::InvalidValue when the mandatory reference is unset, and with the reference errors when it dangles or names another type.

pub fn subsequent_applied_loads( &self, ) -> StructuralResult<Option<Vec<StaticLoad<'m, 's>>>>

SubsequentAppliedLoads, the loads after the inherited AppliedLoad, in list order and projected as StaticLoad.

None for a non-varying action and under IFC4/IFC4X3. The schema minimum is enforced: LIST [1:?] on the linear form, LIST [2:?] on the planar form, otherwise StructuralError::InvalidCardinality. A list member that dangles fails with StructuralError::DanglingReference; one that is not an IfcStructuralLoad fails with StructuralError::WrongReferenceType. The derived VaryingAppliedLoads is AppliedLoad followed by this list.

impl<'m, 's> StructuralAction<'m, 's>

pub fn id(&self) -> EntityId

The IfcStructuralAction entity id.

pub fn kind(&self) -> ActionKind

Which application geometry this action carries.

pub fn applied_load(&self) -> StructuralResult<EntityId>

AppliedLoad, the IfcStructuralLoad this action applies.

Fails with StructuralError::WrongReferenceType if the referenced load’s type is not one of the subtypes this action’s kind permits (e.g. a point action must reference IfcStructuralLoadSingleForce or IfcStructuralLoadSingleDisplacement), and with StructuralError::SemanticViolation for the same schema-shape checks validate_semantics performs.

pub fn coordinate_system(&self) -> StructuralResult<CoordinateSystem>

GlobalOrLocal, always present on IfcStructuralAction.

pub fn destabilizing_load(&self) -> StructuralResult<Option<bool>>

DestabilizingLoad, mandatory in IFC2X3 (defaults to Some) and optional in IFC4/IFC4X3.

None when the attribute does not exist for this type in this schema version.

pub fn caused_by(&self) -> StructuralResult<Option<EntityId>>

CausedBy, the IfcStructuralReaction that produced this action, when the attribute exists and is set.

pub fn predefined_type(&self) -> StructuralResult<Option<&'m str>>

PredefinedType, when the attribute exists for this action’s IFC type.

IfcStructuralPointAction has no PredefinedType attribute, so this returns None for point actions regardless of schema version.

pub fn projected_or_true(&self) -> StructuralResult<Option<&'m str>>

ProjectedOrTrue, mandatory on linear/planar actions in IFC2X3 and optional elsewhere.
