Why no bracket was produced.

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.

Route(RouteError)

The subregion is malformed, or a predicate was undecidable.

InvalidTolerance

The tolerance is negative or not finite.

CrossingObstacles

Two walls or barriers cross other than at a shared vertex. The free space is triangulated with them as constraints, and crossings would need rounded vertices; not supported yet.

Triangulation

The free space could not be triangulated, or a triangle of it is too thin to hold a point strictly inside.

Unreachable

Part of the subregion lies in free space that no target reaches, so its farthest distance is infinite. The triangle lies in the free space and meets the subregion; no target reaches any of it.

Fields

triangle: [Point2; 3]

The triangle’s corners.

Empty

The subregion does not meet the free space.

MismatchedMaps

Two distance maps cover different free space: their regions or barriers differ.
