Enum ChainPiece2 

#[non_exhaustive]
pub enum ChainPiece2 {
    Intrinsic {
        curvature: CurvatureLaw,
        length: f64,
    },
    Parametric {
        curve: Curve2,
        start: f64,
        length: f64,
    },
}

One piece of a Chain2, written in its own local frame: origin at the piece start, +x along the start tangent.

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.

Intrinsic

A natural-equation piece: curvature as a function of arc length from the piece start, over length.

Fields

curvature: CurvatureLaw

Curvature law, in the piece’s own arc length.

length: f64

Arc length of the piece.

Parametric

A parametric curve read by arc length.

curve is written in the piece’s local frame: it passes through the origin at parameter start with its tangent along +x there, and the piece is the stretch of it from start, in increasing parameter, whose arc length is length.

Fields

curve: Curve2

The curve, in the piece’s local frame.

start: f64

Curve parameter where the piece begins.

length: f64

Arc length of the piece along curve.
