Crate aequora_scope 

Authorized, versioned, database-neutral synchronization datasets.

A scope is a server-issued authorization contract, never an arbitrary client query. This crate defines identity, cursor validation, resolver, membership, projection, subscription, and transition semantics without importing a database or transport implementation.

Structs

DatasetPartitionId

Stable, bounded partition selected by a server-owned scope definition.

EvaluatedJournalEntry

One authoritative journal entry evaluated by a server-owned scope filter.

FilteredScopePage

Filtered delivery plus a watermark through all evaluated entries, including excluded ones.

LocalScopeState

Serializable reference model used by adapters and compliance tests.

MembershipRecord

One active entity-to-scope reference.

ProjectionVersion

Versioned projection namespace. Different field visibility must never be merged accidentally.

ResolvedScope

Complete authoritative binding returned by a registered resolver.

ScopeBootstrapPlan

Scope-bound bootstrap plan; activation still requires an atomic ScopeTransition.

ScopeCursor

A journal watermark meaningful only with its complete scope binding.

ScopeDefinitionId

Stable application-assigned scope-definition identity. Zero is reserved.

ScopeDescriptor

Canonical server-owned dataset descriptor; it contains no raw SQL or executable predicate.

ScopeGeneration

Incompatible authority timeline generation for one scope.

ScopePrincipal

Trusted authenticated identity supplied to a scope resolver by the server boundary.

ScopeRegistry

Definition registry that rejects duplicate identifiers and unknown client requests.

ScopeRemoval

Scope-local removal, deliberately distinct from a domain tombstone.

ScopeRequest

Bounded client request for one registered definition. Parameters are opaque to the core.

ScopeStatus

Payload-free status suitable for a negotiated scope control message.

ScopeTransition

Retry-stable atomic transition input for a local adapter.

ScopeTransitionId

Retry-stable identity of one scope transition.

ScopeTransitionOutcome

Result of one idempotent transition application.

ScopeVersion

Version of membership rules for one scope.

Subscription

Durable relationship between a client and one resolved scope.

SubscriptionId

Durable identity of one client subscription.

Enums

CursorValidity

Server result for one bound cursor.

LocalRetentionPolicy

Local retention behavior for data leaving an active scope.

MembershipDecision

Deterministic membership result for an authoritative entity/event.

PendingIntentDisposition

Explicit disposition of pending intent affected by authorization loss.

ScopeBootstrapMode

Safe bootstrap strategy for a version transition.

ScopeError

Scope semantic failure.

ScopeRemovalReason

Why membership ended without deleting the authoritative domain entity.

ScopeServerState

Current server view of one subscription.

ScopeTransitionInstruction

Versioned server instruction. Legacy peers safely map non-continue instructions to full resync.

ScopeTransitionKind

Coherent transition category.

SubscriptionState

Durable client subscription lifecycle.

Traits

MembershipEvaluator

Pure application membership boundary.

ProjectionRule

Authorized projection boundary. None means the entity must not be delivered.

ScopeResolver

Server-owned asynchronous scope resolution contract.

ScopeResourceAuthorizer

Authorization hook for blobs, integrity manifests, search indexes, or other scope-bound resources. Possessing a stale resource identifier never grants access by itself.

Functions

project_filtered_page

Applies a deterministic authorized projection while advancing through intentionally excluded journal entries.
