Enum PieceSource 

#[non_exhaustive]
pub enum PieceSource {
    Obstacle {
        polygon: usize,
        ring: usize,
        edge: usize,
    },
    Barrier {
        barrier: usize,
    },
    Bridge {
        bridge: usize,
    },
}

The input an edge of a free face lies on.

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.

Obstacle

An edge of an obstacle. Ring 0 is the outer ring, k >= 1 is holes[k - 1]; the edge leaves points[edge].

Fields

polygon: usize

Index into FreeSpaceInput::obstacles.

ring: usize

The ring of the polygon.

edge: usize

The edge of the ring.

Barrier

A barrier, by index into FreeSpaceInput::barriers.

Fields

barrier: usize

The index.

Bridge

A bridge the operation added, by index into FreeFaces::bridges.

Fields

bridge: usize

The index.
