Struct ElementRecord 

pub struct ElementRecord {
    pub global_id: GlobalId,
    pub class: IfcClass,
    pub name: Option<String>,
    pub object_type: Option<String>,
    pub placement: Placement,
    pub container: Option<GlobalId>,
    pub type_ref: Option<GlobalId>,
    pub properties: PropertySets,
    pub representation: Option<Representation>,
    pub bounds: Option<BoundingBox>,
    pub representation_revision: u64,
    pub semantic_revision: u64,
}

One element in the model.

The two revision counters are what make incremental work possible: a rename bumps only semantic_revision, so the renderer never rebuilds a mesh for it (docs/ifc-semantics.md §5, “incremental invalidation”).

Fields

global_id: GlobalId

class: IfcClass

name: Option<String>

object_type: Option<String>

placement: Placement

container: Option<GlobalId>

IfcRelContainedInSpatialStructure — the storey or space holding this element.

type_ref: Option<GlobalId>

IfcRelDefinesByType — the family type this instance is defined by.

properties: PropertySets

representation: Option<Representation>

Geometry in local space, evaluated from the family recipe. None for spatial structure elements and for anything not yet flexed.

bounds: Option<BoundingBox>

World-space bounds, once geometry has been evaluated.

representation_revision: u64

Bumped when geometry must be rebuilt.

semantic_revision: u64

Bumped when metadata changes but geometry does not.

Implementations

impl ElementRecord

pub fn new(global_id: GlobalId, class: IfcClass) -> Self

pub fn with_name(self, name: impl Into<String>) -> Self

pub fn with_placement(self, placement: Placement) -> Self

pub fn with_container(self, container: GlobalId) -> Self

pub fn with_representation(self, representation: Representation) -> Self

Trait Implementations

impl Clone for ElementRecord

fn clone(&self) -> ElementRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ElementRecord

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ElementRecord

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ElementRecord

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ElementRecord

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
