Enum PathBound 

#[non_exhaustive]
pub enum PathBound {
    Parameter(Scalar),
    Point(Point3),
}

Where a PathPiece starts or ends when its distance is not stated (#304): the evaluator resolves it to a distance in the curve’s station measure; see the module documentation.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Parameter(Scalar)

At the curve’s native parameter (a closed conic’s angle, a B-spline’s knot-domain parameter, a polyline’s segment index plus fraction, a line’s t along its direction).

Point(Point3)

At the point of the curve, in the curve’s own coordinates (before the piece’s placement; z = 0 on a 2D curve). It must lie on the curve, and only one parameter may name it.
