Crate uqa_storage 

Persistent and in-memory backing stores for UQA: documents, inverted index, vector indexes (IVF), B-tree, in-memory spatial scan, block-max, and the provider-neutral catalog and transaction contracts.

Modules

analyzer_binding

Durable, independently resolved analyzer sides and their field owner.

backend

Persistent storage backend factory.

block_max_index

Per-block maximum score index for Block-Max WAND optimisation.

btree_index

In-memory B-tree index for predicate scans.

catalog

Backend-neutral persistent catalog facade.

catalog_index_keys

Storage preserves opaque SQL expressions; the engine owns their dependencies and rewrites.

clustered_postings

Backend-neutral clustered posting codec and lazy score cursor.

document_store

Document storage abstraction.

encryption_key

Explicit, non-serializable key propagation between persistent storage owners.

hnsw_index

Hierarchical Navigable Small World vector index.

index_abc

Common contract every index implementation honours.

index_manager

Index manager: registry that creates / drops / looks up indexes.

index_types

Index type definitions for the storage layer.

inverted_index

Inverted index abstraction and an in-memory implementation.

ivf_index

In-memory inverted-file vector index.

key_value

Backend-neutral Key/Value storage.

read_control

Query-owned provider reads share allocation limits and cancellation with their consumers.

spatial_index

In-memory spatial index over geographic points.

term_key

Canonical binary posting keys for scalar strings and unpaired UTF-16 terms.

transaction

In-memory transaction snapshots and shared transaction errors.

vector_index

Vector index abstraction and an in-memory brute-force fallback.

Structs

CatalogIndexRow

One row from the secondary-index registry.

FtsIndexStat

RelationIdentity

Durable identity of a SQL relation.

SchemaAclEntry

One explicit schema ACL path. None on SchemaRow::acl retains the owner-only default privileges of an ordinary newly created schema.

SchemaPrivileges

Grantable privileges carried by one schema ACL path.

SchemaRow

Durable schema ownership and ACL metadata.

SequenceAclEntry

One explicit sequence ACL path. None on SequenceRow::acl retains PostgreSQL’s default owner-only privileges.

SequenceOwner

Stable owner identity for a sequence dependency. Names are deliberately excluded so table and column renames do not require dependency rewrites.

SequencePrivileges

Grantable privileges carried by one sequence ACL path.

TableAclEntry

One explicit table-shaped relation ACL path. Legacy entries without an explicit grantor originate from the relation owner.

TablePrivileges

Grantable privileges carried by one table-shaped relation ACL path.

Enums

SequenceOwnerDependency

Dependency strength of a sequence owner. Ordinary OWNED BY and SERIAL use an automatic dependency, while an identity column owns its sequence through an internal dependency that cannot be reassigned or dropped directly.
