Struct Objective 

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

Strict borrowed projection, read against one release.

Implementations

impl<'m> Objective<'m>

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

Construct from an entity of the exact expected kind, read against release.

ConstraintView binds the model’s declared release; use this when the release is known some other way.

Errors

WrongEntityType for another entity, UnsupportedSchema for a release this crate is not verified against (IFC4X1, IFC4X2), and EntityNotInSchema for an entity the release does not declare.

pub const fn id(self) -> EntityId

Stable model identifier.

pub const fn release(self) -> SchemaVersion

The release this projection reads against.

impl<'m> Objective<'m>

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

Constraint name.

pub fn description(self) -> ConstraintResult<Option<&'m str>>

Optional description.

pub fn grade(self) -> ConstraintResult<ConstraintGrade>

Typed constraint grade.

pub fn source(self) -> ConstraintResult<Option<&'m str>>

Optional source label.

pub fn creating_actor(self) -> ConstraintResult<Option<EntityId>>

Optional creating actor.

pub fn creation_time(self) -> ConstraintResult<Option<&'m str>>

Optional creation time, IFC4/IFC4X3 IfcDateTime text. An IFC2X3 IfcDateTimeSelect record is StructuredValue with the record’s id, never read as text.

pub fn user_defined_grade(self) -> ConstraintResult<Option<&'m str>>

Optional user-defined grade.

impl<'m> Objective<'m>

pub fn benchmark_values(self) -> ConstraintResult<Option<Vec<EntityId>>>

Optional ordered benchmark constraints.

BenchmarkValues is a LIST from IFC4 on: the authored order is significant and returned unchanged, never sorted or deduplicated. IFC2X3 declares a single IfcMetric, returned as a one-element list.

pub fn logical_aggregator(self) -> ConstraintResult<Option<LogicalOperator>>

Optional typed logical aggregator. NotInSchema in IFC2X3, whose ResultValues in that position is an IfcMetric, not an operator.

pub fn qualifier(self) -> ConstraintResult<ObjectiveQualifier>

Typed objective qualifier.

pub fn user_defined_qualifier(self) -> ConstraintResult<Option<&'m str>>

Optional user-defined objective qualifier.

Trait Implementations

impl<'m> Clone for Objective<'m>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'m> Copy for Objective<'m>

impl<'m> Debug for Objective<'m>

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

Formats the value using the given formatter.
