A single durable edit.

Variants

CreateElement

Insert an element. Boxed because this variant is far larger than the others and would otherwise inflate every command in the log.

Fields

element: Box<ElementRecord>

DeleteElement

Fields

global_id: GlobalId

SetName

Fields

global_id: GlobalId

name: Option<String>

SetProperty

Fields

global_id: GlobalId

set: String

name: String

value: Option<PropertyValue>

None clears the property.

MoveElement

Translate an element. Kept distinct from SetPlacement because its inverse is exact without reading the current state.

Fields

global_id: GlobalId

delta: DVec3

SetPlacement

Fields

global_id: GlobalId

placement: Placement

AssignContainer

IfcRelContainedInSpatialStructure.

Fields

global_id: GlobalId

container: Option<GlobalId>

SetRepresentation

Attach evaluated geometry. None clears it.

A command rather than a cache write, unlike bounds: the representation is what gets exported to IFC, so it is part of the model and belongs in the audit trail.

Fields

global_id: GlobalId

representation: Option<Box<Representation>>

AssignType

IfcRelDefinesByType — bind an instance to a family type.

Fields

global_id: GlobalId

type_ref: Option<GlobalId>

AddVoid

IfcRelVoidsElement — an opening cuts its host.

Fields

host: GlobalId

opening: GlobalId

RemoveVoid

Fields

host: GlobalId

opening: GlobalId

AddFill

IfcRelFillsElement — a door or window fills an opening.

Fields

opening: GlobalId

filler: GlobalId

RemoveFill

Fields

opening: GlobalId

filler: GlobalId

Implementations

impl ModelCommand

pub fn primary_target(&self) -> &GlobalId

The element this command is about, for permission checks and change reporting.

pub fn invalidates_geometry(&self) -> bool

Whether applying this command requires geometry to be rebuilt.

A rename must not invalidate a mesh — that distinction is the whole point of tracking semantic_revision separately from representation_revision.

Trait Implementations

impl Clone for ModelCommand

fn clone(&self) -> ModelCommand

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModelCommand

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ModelCommand

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ModelCommand

fn eq(&self, other: &ModelCommand) -> 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 ModelCommand

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for ModelCommand
