Enum ElementRole 

pub enum ElementRole {
    Segment,
    Fitting,
    Terminal,
    Controller,
    MovingDevice,
    StorageDevice,
    TreatmentDevice,
    EnergyConversionDevice,
    Other,
}

What kind of flow element this is, by schema ancestry.

Variants

Segment

IfcFlowSegment – pipe, duct, cable. Carries flow between two points.

Fitting

IfcFlowFitting – elbow, tee, reducer. Joins segments.

Terminal

IfcFlowTerminal – radiator, diffuser, outlet. An endpoint.

Controller

IfcFlowController – valve, damper, switch.

MovingDevice

IfcFlowMovingDevice – pump, fan.

StorageDevice

IfcFlowStorageDevice – tank, cylinder.

TreatmentDevice

IfcFlowTreatmentDevice – filter, interceptor.

EnergyConversionDevice

IfcEnergyConversionDevice – boiler, chiller, heat exchanger.

Other

A distribution element with no more specific flow role.

Implementations

impl ElementRole

pub fn of( model: &Model, element: EntityId, ) -> Result<Option<Self>, SchemaResolutionError>

Classify an element by walking its supertype chain.

Ancestry, not exact type: a file states IfcPipeSegment, never IfcFlowSegment, because the concrete subtypes are what exporters write. An exact-type match finds nothing in a real file.

Ancestry is read against the release the model declares. IFC2X3 has no IfcPipeSegment: its files state IfcFlowSegment itself, and a record name the declared release does not define has no role.

Ok(None) when element is absent or not a distribution element.

Errors

SchemaResolutionError when the model’s FILE_SCHEMA binds no release this crate is verified for (see crate::schema_of).

pub fn is_endpoint(self) -> bool

Whether this role is expected to terminate a run rather than pass through.

Advisory only. A terminal with two ports is unusual, not illegal, and this is used to describe a file rather than to reject one.

impl Eq for ElementRole

impl Ord for ElementRole

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.
