Crate quipu_core 

quipu-core

Embedded, OS-independent audit-log storage engine.

• Append-only segment files with CRC framing (pure std::fs, no OS-specific APIs)
• Typed, versioned entity/actor registries (search by current or past attribute values; logs always render the values as they were at record time)
• Per-field protection: SHA-256 hashing (searchable) or RSA-OAEP encryption
• Custom audit-log columns (text / number / json) managed through a registry
• Retention windows enforced by whole-segment drops

The async event pipeline, filters, DLQ and HTTP proxy live in quipu-middleware; this crate is the synchronous storage and query core underneath it.

Modules

access

Meta-audit (“access log”): records of reads and administrative actions against the audit store itself — who queried what, who ran a redrive or a retention pass. In regulated environments (HIPAA access reports, financial audit-trail reviews) the act of looking at audit data is itself auditable.

checkpoint

Signed integrity checkpoints.

crypto

error

id

merkle

Append-only Merkle history tree (RFC 6962 / Certificate Transparency).

merkle_log

Persistent append-only spine for the crate::merkle history tree.

model

query

registry

retention

schema

storage

Append-only segment storage.

store

time

UTC timestamps as plain u64 microseconds since the unix epoch. Everything is UTC+0 by construction; formatting is done with the classic civil-from-days algorithm so no platform/locale code is involved.
