routing.core._types

Note

This module was named routing.core.types before v2.9.1. The leading underscore now marks it as internal: the type aliases below (Index3D, Coord3D, MatrixType, …) appear in design-rule callback signatures but are rarely imported directly. If your code imported them from the old path, update the import:

# before v2.9.1
from routing.core.types import Index3D, Coord3D

# v2.9.1 and later
from routing.core._types import Index3D, Coord3D
