Struct CantLayout 

#[non_exhaustive]
pub struct CantLayout {
    pub entity: EntityId,
    pub rail_head_distance: f64,
    /* private fields */
}

One resolved, ordered, continuity-checked cant 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 IfcAlignmentCant entity this layout was resolved from.

rail_head_distance: f64

RailHeadDistance: track gauge used to convert cant to superelevation angle, in metres.

Implementations

impl CantLayout

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

Resolve IfcAlignmentCant#entity’s nested IfcAlignmentSegment chain into an ordered, continuity-checked cant profile.

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

Segments in authored (distance-along) order.

pub fn length(&self) -> f64

Total distance-along span covered by this profile.

pub fn cant_at_distance( &self, distance_along: f64, ) -> AlignmentResult<CantAtStation>

Cant at an absolute distance-along value within this profile’s span.
