vibespatial.spatial.index_backends¶

Operation capabilities for coexisting spatial-index execution backends.

Layouts are reusable state; accelerators such as point grids and segment BVHs are strategies within those layouts. The public API chooses by operation and reports the selected implementation through normal dispatch events.

Attributes¶

INDEX_BACKEND_CAPABILITIES

Classes¶

`SpatialIndexBackend`	Enum where members are also (and must be) strings
`IndexBackendCapability`

Functions¶

nearest_backend(→ SpatialIndexBackend)

Choose a nearest contract; individual backends validate family admission.
