Struct Member 

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

Borrowed projection of an IfcStructuralMember (curve or surface, constant or varying).

Implementations

impl Member<'_, '_>

pub fn is_varying(&self) -> bool

Whether the entity is one of the varying-member marker subtypes.

pub fn subsequent_thicknesses(&self) -> StructuralResult<Option<Vec<f64>>>

IFC2X3 surface-varying thicknesses after the inherited first thickness.

IFC4 and IFC4X3 retain the varying subtype as a marker without these attributes, so this returns None for those schemas and for curve members.

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

IFC2X3 shape aspect locating the varying surface-member thicknesses.

Returns None when the selected schema does not declare this attribute.

impl<'m, 's> Member<'m, 's>

pub fn id(&self) -> EntityId

The IfcStructuralMember entity id.

pub fn kind(&self) -> MemberKind

Which curve/surface, constant/varying subtype this member carries.

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

Name, inherited from IfcRoot. Legally absent.

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

PredefinedType, always mandatory on IfcStructuralMember.

Fails with StructuralError::SemanticViolation if the value is USERDEFINED but ObjectType is unset (IFC4/IFC4X3 only; IFC2X3 declares no PredefinedType semantic constraint here).

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

Axis, the local member axis direction. Only meaningful for curve members; returns None for surface members or when the attribute is unset.

pub fn thickness(&self) -> StructuralResult<Option<f64>>

Thickness, the constant surface thickness. Only meaningful for surface members; returns None for curve members or when the attribute is unset. Fails with StructuralError::SemanticViolation if present but not a positive finite value.

Trait Implementations

impl<'m, 's> Clone for Member<'m, 's>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'m, 's> Copy for Member<'m, 's>

impl<'m, 's> Debug for Member<'m, 's>

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

Formats the value using the given formatter.
