Module codec_dispatch 

Per-collection codec selection. Wraps the generic HnswCodecIndex<C> for codecs other than Sq8 (which retains its specialised fast path in quantize.rs / search.rs).

Enums

CollectionCodec

One built codec-index per collection (other than Sq8). Variants match the publicly-selectable quantization choices that route through HnswCodecIndex.

Functions

build_collection_codec

Build a CollectionCodec from a quantization tag and training vectors.
