Enum ConstructionMethod 

pub enum ConstructionMethod<Point, Input, Error> {
    FromData {
        points: BTreeSet<Point>,
    },
    Parametric {
        f: Box<dyn Fn(Input) -> Result<Point, Error> + Send + Sync>,
        params: ConstructionParams,
    },
}

Defines methods for constructing geometric objects.

This enum provides two primary approaches to creating geometric objects:

• Direct construction from a set of predefined points
• Parametric generation using a mathematical function

The generic parameters allow flexibility in the types of points and input parameters used:

• Point: The type representing a coordinate in the geometric space
• Input: The parameter type passed to parametric functions (typically Decimal for 2D or (Decimal, Decimal) for 3D)
• Error: The error the parametric generator reports. crate::geometrics::GeometricObject::construct binds it to the object’s own Self::Error, so a generator for a crate::curves::Curve returns crate::error::CurveError and one for a crate::surfaces::Surface returns crate::error::SurfaceError. The generator’s own failure travels in that type’s Generator variant, which keeps the original cause as its source rather than flattening it at the construction boundary.

Variants

FromData

Construct a geometric object from an explicit set of points.

This method uses a sorted collection of points to directly define the geometry without requiring any computation.

Fields

points: BTreeSet<Point>

Ordered collection of points that define the geometric object

Parametric

Construct a geometric object using a parametric function.

This method generates points by evaluating a mathematical function at specific parameter values defined by the construction parameters.

Fields

f: Box<dyn Fn(Input) -> Result<Point, Error> + Send + Sync>

Function that maps from parameter space to point coordinates. Must be thread-safe to support parallel computation.

It reports the constructed object’s own error type, so a failure reaches the caller as the variant the generator raised instead of being flattened into a string at the construction boundary.

params: ConstructionParams

Parameters defining the domain for sampling the parametric function
