Struct VerticalLayout 

#[non_exhaustive]
pub struct VerticalLayout {
    pub entity: EntityId,
    /* private fields */
}

One resolved, ordered vertical profile.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

entity: EntityId

The IfcAlignmentVertical entity this layout was resolved from.

Implementations

impl VerticalLayout

pub fn resolve( model: &Model, entity: EntityId, units: AlignmentUnits, ) -> AlignmentResult<Self>

Resolve IfcAlignmentVertical#entity’s nested IfcAlignmentSegment chain into an ordered profile.

Checks what the segments state directly: they are contiguous and ascending in StartDistAlong, at the SeamTolerance the model declares, and a zero-length segment stands only in last place. The height seam needs each segment’s elevation law and is checked by profile_law when the profile is lowered. A grade break is recorded in Self::seams, not refused: IFC4.3 does not require vertical seams to be tangential.

Errors

Refuses a model that is not IFC4X3, an entity that is not an IfcAlignmentVertical, an invalid declared Precision, a layout nesting no segment, a segment that does not read, a gap or overlap (AlignmentError::InvalidSegment), and a zero-length segment that is not last or is the only one (AlignmentError::SemanticViolation).

pub fn seams(&self) -> &[VerticalSeam]

Every seam between consecutive segments of positive length, in order, with how the grade continues across it.

pub fn require_tangential(&self) -> AlignmentResult<()>

Demand a tangent profile: refuse the first grade break.

IFC4.3 does not require vertical seams to be tangential, so Self::resolve accepts grade breaks. A consumer whose model needs a continuous grade (a design check, say) asks for it here.

Errors

AlignmentError::ProfileDiscontinuity with ProfileSeam::Gradient at the first grade break.

pub fn segments(&self) -> &[VerticalSegment]

Segments in authored (distance-along) order.

pub fn start_dist_along(&self) -> f64

Distance along where the profile starts.

pub fn length(&self) -> f64

Total distance-along span covered by this profile.
