pub const FACE_RULE_SET: [[(Rotation, i8, i8); 6]; 6];Expand description
Ruleset for converting an S2Point from a face to another.
While this this set includes opposite side faces, without axis mirroring,
it is not technically accurate and shouldn’t be used. Instead, data should let two points travel
further than a full face width.
FACE_RULE_SET[target_face][currentFace] = [rot, x, y]
