Module mbr 

Per-tile Minimum Bounding Region + per-attr statistics.

The MBR is recorded in the tile footer and indexed at the segment level via R*-tree, so a slice query can prune entire tiles before any payload is decoded.

Structs

MbrBuilder

Builder that folds cells into running per-dim min/max and per-attr stats. Use one builder per tile during write-side accumulation.

TileMBR

Tile-level MBR. dim_mins / dim_maxs carry one bound per schema dimension; nnz is the count of populated (non-tombstoned) cells; attr_stats is parallel to the schema’s attrs.

Enums

AttrStats

Per-attribute summary used for predicate pushdown.
