pub fn station_length2(curve: &Curve2) -> GeomResult<Option<Scalar>>Expand description
The length a station on a 2D curve is measured against: None for a
line (unbounded), one turn for a circle or an ellipse, the arc length
of its domain for a polyline or a B-spline, the stated length of an
intrinsic curve or a chain.
§Errors
Any other family, a chain without a valid length, and the quadrature’s refusals, by name.
