Projection that rejects grade lowering.

OrdinalProjection

Outcome projection backed by SqlOutcome.

PostgresBackend

Postgres backend marker.

SqlxFragment

Trusted SQL plus ordered bind values for one SQLx backend.

SqlxLowerer

SQLx lowerer for gatekeep residual policies.

Enums

SqlxDriver

Supported SQLx database driver.

SqlxDriverError

Database driver configuration error.

SqlxValue

Scalar value carried by a lowered SQL fragment.

Traits

GatekeepSqlxBackend

SQLx backend supported by gatekeep lowering.

OutcomeProjection

Projection strategy for turning outcomes into SQL fragments.

PgFactPredicates

Maps a residual fact to a trusted Postgres predicate over the candidate row.

SqlOutcome

Maps a policy outcome to a total-order SQL ordinal.

SqlxFactPredicates

Maps a residual fact to a trusted predicate over the candidate row.

Functions

infer_enabled_driver_from_url

Infers the SQLx driver from a database URL or SQLx-style SQLite memory URL.

validate_database_url_for_backend

Validates that a database URL matches a selected backend.

Type Aliases
