Module backend 

Backend implementations for Eidetica storage

This module provides the core BackendImpl trait and various backend implementations organized by category (database, file, network, cloud).

The BackendImpl trait defines the interface for storing and retrieving Entry objects. This allows the core database logic (Instance, Database) to be independent of the specific storage mechanism.

Instance wraps BackendImpl in a Backend struct that provides a layer for future development.

Modules

database

Database-style backend implementations

errors

Database error types for the Eidetica backend.

Structs

InstanceMetadata

Persistent public metadata for an Eidetica instance.

InstanceSecrets

Private secrets for an Eidetica instance.

ProjectionDescriptor

Identifies a Store’s cached record format.

RecordPage

One bounded ordered scan page. next is the last returned key and must be supplied as the exclusive continuation on the next request.

StagingToken

Opaque token for one private unpublished build.

StoreStateRequest

Metadata used to resolve or build cached state.

Enums

CacheScope

Trust/visibility scope for a cached CRDT state entry.

Reachability

Verdict of a bounded, tree-scoped reachability query (check_targets_reachable_from).

StoreStateLifecycle

Lifecycle of stored Store state.

VerificationStatus

Verification status for entries in the backend.

Traits

BackendImpl

BackendImpl trait abstracting the underlying storage mechanism for Eidetica entries.

Type Aliases

RecordMutations

Ordered record changes.
