Module batcher 

Types for consolidating, merging, and extracting columnar update collections.

Structs

Chunker

A chunker to transform input data into sorted columns.

ColumnChunker

A chunker that consolidates Column<(D, T, R)> updates into sorted Column chunks, without round-tripping through columnation.

ColumnMerger

Counterpart to ColInternalMerger (which merges ColumnationStack chunks). Drives the merge batcher with Column-shaped chunks, no columnation detour, by way of the inherent merge_from / extract methods on Column<(D, T, R)> below.

Functions

drain_side 🔒

Drain remaining items from one side into result / output.

empty_chunk 🔒

Pop a chunk from stash or allocate a fresh one. Stashed chunks are already cleared via recycle_chunk, so they’re ready for push.

gallop 🔒

Advance *lower past every position in [*lower, upper) where cmp returns true.

recycle_chunk 🔒

Reset chunk to an empty Typed and push it to stash for reuse.
