Modules

__codegen

Generated-code SPI for TypeBridge.

aggregate

Typed reduction terms and tuple decoding for the query facade (Flight 3, F3-04b-3).

error

Error handling for the public TypeBridge client.

hooks

Generated-model CRUD lifecycle hooks.

migration

Generated-package-owned immutable migration catalog inspection.

model

Model traits and owner-branded tokens for generated TypeBridge models.

schema

Schema package markers and type-branded installation handshake.

session

Database session handles and connection options.

value

Client-owned canonical query literals (Flight 3, F3-02).

Structs

AnswerCancellation

Cloneable cooperative cancellation signal checked between provider items and used to wake in-flight provider awaits.

Binding

One schema/model-branded Copy binding token allocated by a QuerySession. Copying preserves the binding identity; only a fresh session binding call creates a new occurrence.

BoundField

One generated field resolved against one session binding occurrence.

BoundRole

One generated relation role resolved against one relation binding occurrence.

CanonicalCodecLimits

Tighten-only structural and byte ceilings for canonical codec work.

CanonicalCodecOptions

One owned cancellation/deadline/limit policy captured for a codec invocation.

Collected

One typed collection selection used inside a distinct-root page shape.

DirectConnectionPolicy

Immutable generated-package direct connection policy.

DirectTls

Closed TLS policy for one generated-package direct connection.

EntityManager

Schema-bound, model-branded manager for exact entity operations. Exact reads and writes exclude subtypes; methods return client input/schema-validation, database/transaction/close, or hydration/model-validation errors as applicable.

EntitySubtypeManager

Read-only, schema/model-branded manager for an inclusive generated subtype association. Results are the generated associated leaf or closed family type; no writes are exposed. Reads and counts can return input/schema-validation, database/transaction/close, or hydration/model-validation errors.

Exact

Exact-match selection: results materialize as the bound concrete model.

FieldGroupedQuery

One query lineage grouped by a generated owned field value for aggregation.

GroupedQuery

One query lineage grouped by a second attached binding for aggregation.

MigrationBackfillObservation

Bounded terminal observation for one canonical backfill operation.

MigrationCancellation

Cloneable, wakeable cancellation authority for migration operations.

MigrationExecutionControl

Immutable controls shared by apply and rollback execution.

MigrationExecutionReport

Bounded owned projection of one terminal apply or rollback outcome.

MigrationExecutionResourceLimits

Tighten-only bounded resources for one migration execution invocation.

MigrationVerifyReport

The complete read-only verification report.

NamedSelection

A declaration-ordered named selected shape produced by SelectedRow.

Order

One stable public ordering term over a bound field.

Page

One immutable owned distinct-root page.

PageOptions

Bounded options for one ordered distinct-root page.

Predicate

One schema-branded, composable query predicate.

ProjectedEntityFilter

Immutable canonical filter for one exact generated entity model.

ProjectedRelationFilter

Immutable canonical filter for one exact generated relation model.

Query

One persistent, reusable singular-shape query lineage.

QueryExecutionDeadline

One absolute monotonic deadline shared by every stage of one query terminal.

QueryExecutionResourceLimits

One common tighten-only policy for generated queries in every binding.

QuerySession

One isolated owner-branded query authoring session.

ReadEntityManager

Borrowed read-only manager for one exact generated entity model.

ReadRelationManager

Borrowed read-only manager for one exact generated relation model.

ReadTransaction

One client-owned reusable read transaction over a schema-bound database.

RelationManager

Schema-bound, model-branded manager for exact relation operations. Exact reads and writes exclude subtypes; methods return client input/schema-validation, database/transaction/close, or hydration/model-validation errors as applicable.

RelationSubtypeManager

Read-only, schema/model-branded manager for an inclusive generated subtype association. Results are the generated associated leaf or closed family type; no writes are exposed. Reads and counts can return input/schema-validation, database/transaction/close, or hydration/model-validation errors.

RemoteConnectionOptions

Connection-time authority, transport, and limit configuration.

RemoteDatabase

A client-owned remote generated-query database branded by schema S.

RemoteQueryLimits

Explicit immutable budgets for one remote generated-query terminal.

RowsOptions

Bounded options for one ordered row fetch.

Subtypes

Subtype-inclusive selection: results materialize as the generated leaf or closed family associated with the bound root.

TransactionEntityManager

Schema-bound, model-branded exact entity manager borrowing one open client write transaction. Operations reuse the shared open context and never commit, roll back, or close it; errors are returned with the transaction left open for the caller to decide.

TransactionRelationManager

Schema-bound, model-branded exact relation manager borrowing one open client write transaction. Operations reuse the shared open context and never commit, roll back, or close it; errors are returned with the transaction left open for the caller to decide.

WriteTransaction

One client-owned open write transaction over a schema-bound database.

Enums

MigrationDriftFinding

One verified drift finding.

MigrationExecutionDirection

Direction of one bounded public migration execution report.

MigrationExecutionReportPosition

Stable position vocabulary shared by forward and rollback reports.

MigrationExecutionStatus

Terminal status of one bounded public migration execution report.

ProjectedManagerComparison

One closed scalar comparison admitted by an exact generated-manager filter.
