Crate quiver_core 

Quiver’s storage engine: from-scratch, durable, crash-safe, encrypted-at-rest storage built on 16 KiB pages, a write-ahead log, and a versioned manifest.

This crate owns all durable state (ADR-0004 / ADR-0005) and is deliberately built without an embedded KV/DB engine. Phase 1 ships the foundational primitives; the columnar segment layout, the store-level engine, and crash recovery build on top of them.

• page — the 16 KiB page: the unit of checksum, encryption, and I/O, with a swappable page::PageCodec (plaintext now, AEAD with quiver-crypto).
• wal — the write-ahead log: the durability anchor. An acknowledged write is fsync’d to the log first, so it survives kill -9.
• manifest — the versioned catalog, made current via an atomic write-new + fsync + rename of CURRENT.
• store — the store::Store engine: the write path, checkpointing, and crash recovery that compose the primitives above, over internal sealed segments.
• descriptor — collection schema; ids — typed ids::Lsn / ids::CollectionId.

Modules

descriptor

Collection descriptors: the schema fixed when a collection is created.

error

Error types for the storage engine.

ids

Strongly-typed identifiers used throughout the storage engine.

keyring

The key-supply seam between the storage engine and quiver-crypto.

manifest

The versioned manifest: the catalog and durability anchor.

page

Fixed-size pages: the unit of checksum, encryption, and buffered I/O.

sec

Secondary indexes (.sec): per filterable field, value → roaring bitmap of the rows that hold it, the substrate for pre-filtered (hybrid) search (ADR-0022).

store

The storage engine: a durable, crash-safe vector store per collection.

wal

The write-ahead log: the durability anchor of the storage engine.
