Struct Chain 

pub struct Chain {
    pub points: Vec<Point>,
    pub outward: Vec<Vector>,
    pub closed: bool,
}

One connected polyline of a section.

Fields

points: Vec<Point>

The points, in order along the chain. A closed chain does not repeat its first point at its end.

outward: Vec<Vector>

At each point, the unit direction in the plane pointing out of the material, from the normals of the triangles cut there projected into the plane.

closed: bool

Whether the chain closes on itself: every edge it crosses is shared by two triangles. An open chain ends on the mesh’s boundary or on an edge listed in Section::unlinked.
