Crate postings 

postings

A small inverted-index core built around postings lists.

Scope (deliberate)

• This crate is index-only: it does not store document content.
• It supports candidate generation with no false negatives (a caller may choose to verify candidates with an exact matcher).
• It uses a Lucene-style mental model: immutable “segments” (here: append-only batches) and logical deletes.

Optional modules

• postings::codec: low-level codecs (varint/gap) for postings payloads (in this repo).
• postings::positional (feature positional): positional postings for phrase/proximity evaluation.

Non-goals (for now)

• On-disk persistence / compaction
• Rich query language beyond “union of term postings”
