Struct LineIndex 

pub struct LineIndex(/* private fields */);

IfcLineIndex = LIST [2:?] OF IfcPositiveInteger.

1-based, and that is not a detail

Indices point into an IfcCartesianPointList, and EXPRESS aggregates are 1-based. Rust slices are 0-based. Every index must be decremented exactly once, and doing it twice or not at all shifts the entire polyline by one vertex without any error being raised.

Implementations

impl LineIndex

pub fn as_zero_based(&self) -> &[usize]

Zero-based indices into the point list.

pub fn len(&self) -> usize

How many points this run covers.

pub fn is_empty(&self) -> bool

Is the run empty? Never true for a schema-valid index.
