Struct CartesianPointList2D 

pub struct CartesianPointList2D<'m> { /* private fields */ }

A borrowed view of an IfcCartesianPointList2D.

Implementations

impl<'m> CartesianPointList2D<'m>

pub fn new(id: EntityId, entity: &'m Entity) -> Self

Wrap an entity assumed to be an IfcCartesianPointList2D.

pub fn id(&self) -> EntityId

The entity id.

pub fn coordinates(&self) -> GeometryResult<Vec<[f64; 2]>>

Every coordinate pair, in file order.

A row of the wrong width fails rather than being padded or truncated: the width is what distinguishes this entity from its 3D sibling.

pub fn point(&self, one_based: usize) -> GeometryResult<Option<[f64; 2]>>

The point at a 1-based index, as IFC index attributes write them.

Returns None for 0 or for an index past the end, which is what a malformed IfcIndexedPolyCurve produces and must not panic.
