Enum TrimSelector 

#[non_exhaustive]
pub enum TrimSelector {
    Parameter(Scalar),
    Point2(Point2),
    Point3(Point3),
    ArcLength(Scalar),
}

One trim selector preserved from a source representation.

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)

Curve parameter.

Point2(Point2)

Two-dimensional point.

Point3(Point3)

Three-dimensional point.

ArcLength(Scalar)

Arc length along the basis curve.

Selects the basis parameter at which the arc length along the basis, measured from the basis curve’s parameter 0 in the sense of the trim, equals the value: in increasing parameter when the trim agrees with the basis, in decreasing parameter when it does not. A negative value measures the other way.

The value is exact stored data, and it is a parameter-kind selector: it names a position by a measure along the curve, not by a point, so it satisfies TrimmingPreference::Parameter. Most curves have no closed-form arc length (a cubic parabola’s is elliptic), so an evaluator resolves the parameter by quadrature and a root find to a tolerance it states, and a path that cannot refuses by name.
